Input: Consider Input: It emerged last month that checks had been put on hold so officials could deal with queues at passport control. Critics say efforts to tackle illegal immigration were effectively neglected. But Border Force boss Sir Charles Montgomery told MPs a queue of vehicles was itself a security threat as it was vulnerable to "clandestine" migrants. According to a National Audit Office report published last month, officers were ordered on three successive days to switch from searching for contraband and illegal stowaways to checking passports to prevent big queues building up at Calais and other entry points, ahead of last year's Olympic games. 'Clear rationale' Freight searches were also suspended due to understaffing and to allow staff to have meal breaks, although vehicles continued to be searched by French officials and sniffer dogs used by the Border Force. Sir Charles, a former senior Royal Navy officer who became Border Force boss in March, told the Public Accounts Committee that checks had not been totally abandoned. But he said it was "absolutely right" to shift the resources at the Border Force's disposal where necessary to prioritise "traffic flows" at points of entry. "There is a very clear rationale for this and it is driven by the primary objective of the Border Force which is national security. The flows of traffic approaching Calais are themselves important for security. "The checks and controls can create backlogs of stationary traffic of up to three miles if not properly managed. "Those queues are a primary source of security concern because stationary traffic - particularly soft-sided traffic - are a primary target for the clandestines trying to get through the border." Labour MP Margaret Hodge, who chairs the cross-party committee, questioned why the decision had only come to light in the watchdog's report and why officials had not disclosed what was happening earlier. The Border Force did "not want to put into the public domain the possibility or probability at any given time of checks having been suspended", Sir Charles said. But Mrs Hodge replied: "If I may say so, it is not putting it in the public domain which is wrong, it is the action of suspending it which is wrong... it is the action, not the reporting of the action, which is vital." Manpower The National Audit Office has suggested a lack of manpower was to blame for resources having to be juggled. The number of full-time border staff fell from 8,023 to 7,527 between April 2010 and March 2012. But since separating from the Border Agency, the agency's budget has increased and funding is in place to increase staff numbers to 8,477 by next year. The Border Force was brought under the direct control of the Home Office in 2011, when the UK Border Agency was abolished following a row over the relaxation of passport checks at Heathrow without the authorisation of ministers. Sir Charles told MPs that coach parties of schoolchildren had been subject to less formal checks at Calais this summer under a pilot scheme to reduce delays, the results of which were now being evaluated. The children had not been required to disembark and face-to-face checks had been carried out on the vehicle, he said. He stressed the initiative had been pre-authorised by the Home Office and followed a risk-based analysis.

Output: The UK's most senior immigration official has defended the suspension of customs checks on vehicles at Calais as necessary to protect national security.


Input: Consider Input: The maker of the ground-breaking video game Pong is seeking to separate from its loss making French parent Atari SA. Atari Inc, together with Atari Interactive Inc, Humongous Inc. and California US Holdings Inc. want to secure independent funding to develop digital and mobile games. Atari said in December it was looking to raise cash and was talking to investors. In a statement, the companies said, "with this move the US based Atari operations seek to separate from the structural financial encumbrances of their French parent holding company, Atari SA". Atari SA, formerly known as Infogrames SA has been struggling financially for years. The US operations of Atari have shifted their business from retail games to digital games in recent times and have become a growth engine for Atari SA. "The Chapter 11 process constitutes the most strategic option for Atari's US operations as they look to preserve their inherent value and unlock revenue potential unrealized while under the control of Atari SA," the statement said. Atari's Pong was an arcade game credited with helping kick-start the multi-billion pound video games industry but more recent titles include 'Centipede', 'Missile Command' and Rollercoaster Tycoon'. Neither Atari SA or Atari Inc. were available for comment.

Output: The US operations of Atari have filed for bankruptcy protection.


Input: Consider Input: David Johnston was walking 12-year-old Rosie on Tuesday evening in the Marchburn Drive area when what he described as a bull terrier-type dog "pounced" on his dog. Mr Johnston, 38, said his pet was being shaken "like a rag doll". He said Rosie was eventually freed, but died. Police are investigating and appealed for witnesses. Mr Johnston - who had Rosie since she was eight weeks old - told the BBC Scotland news website: "I was taking her for her daily walk when it happened. A couple of guys were standing with a dog. "All of a sudden the dog did one pounce from a lying position and another onto her. It lifted her clean off the ground and started shaking her like a rag doll. "We tried in vain, the man was kicking his dog to get it to release its grip. Eventually he managed to get its jaws to unlock. "I got hold of Rosie and cradled her. The dog was still trying to attack. I took her back to the house but she was lifeless. We went to the vet but she was dead." 'Traumatic incident' He explained: "We are hoping we can get this dog off the streets. It could have done it before, and could do it again. "Rosie was a very, very happy dog. It should not have happened. She did not deserve that." Police Scotland said officers were appealing for witnesses after the dark brown and black dog attacked the white and brown Jack Russell in Northfield at about 20:30 on Tuesday. PC Brenda Adam said: "In particular I would appeal for any details of two men seen in the area around the time, one wearing a dark coloured T-shirt and bottoms whilst the other was on a bicycle. "This was a traumatic incident for those involved and I urge anyone with information - no matter how insignificant you think it is - to get in touch."


Output: An investigation has been launched after a Jack Russell was mauled to death by another dog in Aberdeen.
