The bomb is believed to have been hidden in an aluminum camera case, planted by an individual carrying a stolen Danish passport issued under the name "Per Anker Hansen". Afterwards, survivors commented that they found it odd that "Hansen" had so zealously guarded his "camera equipment" by wrapping the unwieldy aluminum box in plastic. "Hansen" is believed to have deposited the camera case containing the bomb under the table. News footage showed the suspected bomber gesturing to his camera as if to indicate an equipment malfunction and then leaving the room. The bomber may have detonated the bomb remotely using a walkie-talkie signal. Seconds after "Hansen" left the room, an explosion ripped through the hut, leaving the injured and dying crying out in pain and calling for help the darkness.
