A man has been arrested by police investigating how a fake bomb was transported on a cargo plane from London to Istanbul.
The device, consisting of a wedding cake box with a timer, wires and detonator, was taken to UPS in Camden, north London, two weeks ago.
The Metropolitan Police say they arrested a 26-year-old man on suspicion of making a bomb hoax. He was bailed to return to a north London police station in May. The incident is not believed to be linked to terrorism.
The news comes just months after a bomb disguised as an ink cartridge was found on a UPS cargo plane at East Midlands Airport.
