Sources say a laptop computer concealed a bomb

In a video released by officials, an airport worker takes the laptop and hands it to another employee

(CNN) Somali intelligence officials say two airport workers handled a laptop containing a bomb that later exploded in a passenger plane.

In a video made public on Sunday by officials, one airport worker takes the laptop and hands it to another employee.

The employees then hand it over to a man who was killed when the laptop explosion blew a hole in the plane's fuselage, said Abdisalam Aato, a spokesman for the Somali Prime Minister.

Both workers have been arrested.

Somali officials identified the lone fatality as suspect Abdullahi Abdisalam Borleh. He was sucked out of the airliner through the hole from the blast Tuesday.
