There has been a "minor explosion" at the constituency office of Conservative MP Nick Boles.

A bang and the sound of breaking glass were heard at the junction of North Street and Burghley Street in Bourne, Lincolnshire, shortly before 01:30 BST.

Police said there was only minor damage to the building and no-one was injured. A man has been arrested.

Mr Boles, the Grantham and Stamford MP, said he understood a home-made device had been thrown through a window.

There's enough there to piss someone off unfortunately. On the other hand, it's quite possible someone thought he was Nick Knowles
