Guard at Olympic site held over explosive find
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 in a car park, 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: "This incident did not represent a threat to the safety and security of the site."
