The Massachusetts headquarters for presidential candidate Donald Trump was vandalized overnight Friday.

"You certainly have the right if you don't like a candidate to tell them you don't like them and protest against them," said Littleton Police Chief Matthew King. "But you certainly don't have the right to do a criminal act."

Littleton Police received a report of the vandalism around 9 a.m. Saturday. The Conant Building on King Street houses the state's headquarters of Donald J. Trump for President, Inc.

Police said vandals spray painted multiple words outside of the offices, including vulgar and sexual references, the word "pig" and references that Trump is a Nazi.

"It was pretty vulgar," King said.

Police are investigating the incident and reviewing surveillance footage. They believe the suspect may be on the younger side.

Trump's campaign manager was notified and said it was upsetting someone would do this; volunteers spent the day cleaning the offices, which opened just a week or two ago in the historic Conant Building.
