British police ordered a review of an "incident" on Monday in which a man ran into Prime Minister David Cameron after he had given a speech in an apparent breach of security. Cameron was seen in video images backing away from a man with long dreadlocks running towards him and then being rushed to his car as the man was hustled away by security officers.
The police said in a statement that the 28-year-old was arrested by officers but later released without charge, following the incident in Leeds in northern England.
