Fake Bomb in Cake Box Sneaked Onto UPS Flight

British authorities are investigating how a fake bomb hidden in a wedding cake box was able to make it from the UK to Turkey without being detected. The package, containing a timer, wires, and a detonator, traveled on a UPS flight to Istanbul, reports the BBC. A 26-year-old man has been arrested on suspicion of creating the device.

Experts believe the device—sent less than 6 months after a cargo bomb bound for the US was intercepted in Britain—could have been a trial run for a real terrorist attack, the Independent notes. "We have already begun an investigation which will look at all aspects of this incident, including UPS procedures," a government spokesman said. "The UK has one of the toughest security regimes for air cargo in the world. All security measures are subject to continuous review."
