LONDON, Nov. 17 (UPI) -- British authorities Friday were searching for a lost briefcase containing fake bombs, which spark a security alert if found by the public.
The briefcase was inadvertently left on a train by a City of London police officer after giving a presentation on explosive devices to other officers and security personnel, the Evening Standard reported Friday.
"They are very realistic. If the briefcase went through an x-ray machine you would see fuses and what looks like explosives," the newspaper quoted an unidentified source. "This could cause a massive security panic and chaos if one of these was found on the Tube (London's subway system), or if someone smuggled one onto a plane."
The briefcase was said to contain 15 dummy explosive devices, including a mock-up of the bomb that brought down Pan Am's Flight 103 over Lockerbie, Scotland, in 1988.
The report said the officer carrying the case lost it on Oct. 31 and immediately reported it missing to British Transport Police.
