An explosion at one of Nick Boles’ offices yesterday (Sunday) is believed to have been caused by a homemade device thrown through the window.
The Conservative Grantham MP’s Bourne office, in the Stamford and Grantham Conservative Club in North Street, was targeted at around 1.20am.
Mr Boles said he understood a homemade device had been thrown through the window of the office.
Police said there was no structural damage to the building but a window has been broken.
No-one was injured in the incident.
Police said a 24-year-old man local to the area was arrested in connection with the incident.
A spokesman said early indications suggest this incident is not linked to any wider issues or recent events in the county.
