A man has been arrested briefly by police after he ran into David Cameron as he left a news conference in Leeds.

The man, identified as Dean Balboa Farley, headed towards the Prime Minister at speed, bumping into him in the street outside the city's Civic Hall.

But Mr Cameron's security team stepped in to wrestle the dreadlocked 28-year-old out of the way.

The PM appeared to be alone for several moments before the team got him into a waiting car.

The Metropolitan Police Service (MPS) Specialist Protection Command, which is responsible for the protection of the Prime Minister, has said it will conduct a review of the incident in coordination with West Yorkshire Police.

Video footage shows Mr Cameron appearing to brace himself as the man approached, before a bodyguard intervened to grapple with him.

West Yorkshire Police said there was "nothing sinister" about the incident and it was "just a man in the wrong place at the wrong time".

He is understood to have told officers he was on his way to a local gym. 

Conservative MP Mark Pritchard has demanded a full investigation into how the Metropolitan Police security team allowed the man to get so close to Mr Cameron.

He called for the Met's commissioner Sir Bernard Hogan-Howe to launch an immediate internal inquiry.

He said: "The Met Police have some of the best close protection officers in the world. However, this was a clear breach of security and could have been far more sinister in outcome."

West Yorkshire Police claim that the incident was "just a man in the wrong place at the wrong time" and the man in question says he was just jogging and ran too close.
