Peterborough MP attacked by bus shelter vandal

The MP for Peterborough was attacked by a man who he had attempted to stop vandalising a bus shelter in the city.

Conservative MP Stewart Jackson said he tried to make a citizen's arrest on the man after he threw a bottle of beer at the shelter on Broadway on Saturday.

But the man then kicked Mr Jackson, who had been shopping with his wife and daughter.

Cambridgeshire Police said a 20-year-old man had been arrested.

Mr Jackson said he saw a man throw a full bottle of beer at the shelter which shattered the glass.

"I thought any of the shards could have injured a woman or a child so I tried to make a citizen's arrest," he said.

"He squared up to me and threw a few blows which missed but he swung a kick which made contact but I was not badly injured.

"He then ran away and my wife called the police."
