Guard in Olympics explosives arrest
A female security guard has been arrested near London's Olympic Stadium site on suspicion of possessing explosives and drugs.
The 40-year-old dog handler was held after her vehicle was searched, but police said the incident was not thought to be terror-related.
Scotland Yard said police recovered a very small amount of a substance, which was being forensically examined.
A Scotland Yard spokesman said: "On March 29, acting on information received, police stopped and searched a woman in a car park off Pudding Mill Lane. Her vehicle was searched and a 40-year-old woman arrested on suspicion of possession of an explosive substance and Class A drugs. She is in custody at an east London police station.
"The arrest was made by officers from the Olympic site support unit (OSSU) following information received. The investigation is being carried out by Newham CID.
"The Counter Terrorism Command is aware but the incident is not being treated as terrorism related. This incident did not represent a threat to the safety and security of the site."
The arrest came on the same day that building work at the £486 million Olympic Stadium was completed.
A spokesman for the Olympic Delivery Authority said: "There are robust measures to ensure the safety and security of the Olympic Park.
"We are working with the police in their investigation. At no point has the safety and security of the Olympic Park been put at risk."
A spokesman for security firm G4S, which earlier this month signed a deal to be the official security firm for the Games, said: "Our canine services team is licensed to hold small samples of explosives for training purposes and are required to undertake rigorous training and follow strict operational processes. G4S take breach of operational processes very seriously and are assisting the police with their inquiries in relation to this incident."
