Tory Government minister Nick Boles yesterday condemned an explosives attack on the Conservative Club in Bourne where he has one of his offices.
Unconfirmed reports suggest a home-made device was thrown through a window at the North Street building, although witnesses say they heard two blasts in the early hours of the morning.
Police arrested a 24-year-old local man and he was still helping officers with their inquiries yesterday.
Mr Boles, the Grantham and Stamford MP and planning minister in the Department for Communities and Local Government, said: “Obviously I deplore this act of violence.
“The incident is being investigated by the police and I know everyone will do whatever they can to support the investigation.
“In the meantime, we should all carry on doing our jobs as normal.”
No one was reported hurt in the incident.
A window was smashed but it is believed there was no structural damage to Bourne’s Stamford and Grantham Conservative Club.
Emergency services were called shortly after 1.20am.
Caroline Glithero (49), who lives nearby, said she heard two explosions.
She said: “I heard two very loud bangs and on the second one I went to see what it was and found a lot of debris and a broken window.
Darren Pullen said: “I heard two explosions about ten/15 minutes apart.
“I had a quick look for any smoke/fire but couldn’t see anything, so I thought they were just fireworks being let off.
“I don’t live too far away from Burghley Street.”
Police yesterday were not confirming what type of device was used in the attack.
A spokesman said: “All we can stress is we don’t believe it’s linked to any wider issues.”
