Authorities said security was very tight at the detention centre and conducted an independent study to determine how the fugitive escaped. Deputy Prime Minister Wong Kan Seng acknowledged that a security lapse led to his escape, and that everything was being done to recapture Mas Selamat. The Onraet Road facility has armed guards, high wire fences and CCTV cameras. Reactions to the escape were filled with surprise and disbelief in what Western observers describe as a country where ""security breaches are virtually unheard of"". It brought serious embarrassment to the Singapore government, and many questions raised by the public and the press. Security around the schools in the area was also beefed up to assure worried parents. Indonesia and Malaysia announced that they stepped up their own border security in the wake of this incident. Government authorities received more than 1100 calls on sightings of Mas Selamat. The earliest sighting of him was in a back road near MacRitchie Reservoir leading to Toa Payoh Lorong 1, right behind Braddell View Estates.
