Norway's navy announced on Monday that it will help search for the missing plane of 20th century explorer Roald Amundsen, more than 80 years after his death. Roald Amundsen led the first successful expedition to the South Pole from 1910 to 1912. The search -- scheduled for later this year -- will focus on a 40 square-mile (104 square-kilometer) area of the Arctic Ocean where researchers believe Amundsen's plane crashed in 1928. "If there is something down there, we will find it," said senior Commander Frode Loeseth told CNN. Loeseth said they will be concentrating on finding the plane's wreckage, and do not expect to find any remains. Amundsen, who is a national hero in Norway, led the first successful expedition to the South Pole from 1910 to 1912. He is also credited with being the first person to reach both the North and South Poles. He went missing in June 1928 at the age of 55 while flying to the North Pole for a rescue operation. The location of his disappearance "is one of the remaining unsolved mysteries in our time," a press release from the Norwegian Navy said. Loeseth said the navy will participate in the search along with the Norwegian Aviation Museum; Kongsberg Maritime, a Norwegian maritime technology company; and Context TV, a German TV production company that will document the operation. The search is scheduled to begin the last week of August. There have been several attempts to find the location of Amundsen's crash, most recently in 2004. But this time Norway's navy will be able to scour the depths of the Arctic Ocean with a submarine, named after a character in Norse mythology. "We have one special tool -- Hugin -- that is a state-of-the-art submarine, unmanned, and can search for 18 hours," the commander said. Hugin is the mythological raven that traveled around Earth and informed the Norse god, Odin, of what happened that day. Loeseth said the navy has had the unmanned submarine for some time, but the one that will be used in the search is the Hugin 1000, a "newly modified and upgraded" model. Loeseth would not say how much the operation was expected to cost, or which organization was funding the bulk of the search. He stressed that the partners have an agreement and a budget, and Norwegian taxpayers will not be paying for any part of the search. He said Amundsen's relatives support the project. He noted that it has been five years since the last search for Amundsen's wreckage because "it takes time to raise funding for such projects."

By. Gerard Couzens. and Martin Robinson. Suspect: Nelson Delgado, 25, from Portugal, was held by police after a knifeman went on the rampage outside a club in the party resort of Magaluf. A Portuguese man has been accused of stabbing three Britons and a Spaniard in a Spanish holiday resort after a fight in a nightclub turned into a mass street brawl. Nelson Delgado, 25, from Portugal, was held by police after a knifeman went on the rampage outside a pub in the party resort of Magaluf. He has been remanded in custody after appearing in court. Two of the injured Brits remained in a serious condition in hospital today with stab wounds to their back and abdomen. They are currently in the island's Son Espase and Son Llatzer hospitals. The stabbing happened around 4am on Friday morning, and more than 20 Britons working in the resort were said to have been involved in the brawl. Police believe he mistook his alleged victims for a gang of partygoers wearing Halloween fancy dress who had assaulted his brother hours earlier. Delgado, thought to have grown up in Britain, kept his head bowed as he was led into court by police for a private hearing on Saturday where he was told he was being probed on suspicion of attempted murder. He has not yet been charged with any crime. Magaluf is one of Europe's most popular holiday destination for young Britons, but has been tainted with tragedy in recent years. Crime scene: Police believe Delgado mistook his alleged victims for a gang of partygoers wearing Halloween fancy dress who had assaulted his brother hours earlier. Chaos: Shocked clubbers watch as ambulances arrive at the scene in Magaluf where five Britons were stabbed. Attack: Magaluf is one of Europe's top holiday destinations for young Britons but has been rocked by a series of attacks and deaths in recent years. Questioned: Delgado, who is thought to have grown up in Britain, has been told he is being probed on suspicion of attempted murder. In 2008 a British bar worker was raped, beaten and stabbed after walking home from work and three months ago Thomas Ousby fell to his death from the ninth floor of his hotel. Toxicology tests found no drugs and barely any alcohol in his body and mystery surrounds what he was doing at the hotel and why he was found without shoes, wallet or phone. Tom, an aspiring model and musician from Uxbridge, west London, was said to have ignored a warning from a maintenance man who told him to get down from the outside fire escape of the four-star hotel. He then slipped and fell more than 60ft, landing on a wall. Staff said they had seen him running away from someone shortly before the tragedy. His father John, 49, said: 'If there was foul play we want to know about it. We owe it to Tom. Whether he was chased is crucial to knowing what happened. 'If something happened and made him panic and try to get away - could someone have potentially met Tom  at the top of the roof or the stairs.?'
