A “number of shots” were fired at DUP candidate Sammy Wilson’s office in Northern Ireland, he has said.
Mr Wilson, who is standing to retain his Westminster seat in East Antrim, said the incident happened during the night on Tuesday.
His office in Lancasterian Street, Carrickfergus, had damage to the window, with two round cracks in it.
Police Service Northern Ireland (PSNI) confirmed they are investigating a report “of criminal damage”.
Mr Wilson said: “This was a senseless attack on an office that serves the people of East Antrim.
“Whilst we do not know what sort of weapon was used in the attack it could have caused injury to anyone who happened to be in the area at the time.
“Throughout my years as a public representative, I have never been deterred from putting forward my views and I won’t be deterred now.”
Over the weekend, Labour candidate Stella Creasy’s office in Walthamstow, northeast London, was attacked and “malicious and false leaflets” were circulated.
She vowed to not be “cowed or influenced” by the violence and said whoever made several holes in the glass of her office’s door and window does not “intimidate me and you don’t belong in the political process”.
