Washington (CNN) A Massachusetts state lawmaker was arrested by federal agents early Tuesday on dozens of corruption charges, some of which involve an alleged misuse of campaign funds, the Boston division of the FBI announced.

Massachusetts State Rep. David Nangle, a Democrat, was arrested at his home in Lowell by agents from the FBI and the Internal Revenue Service, according to a tweet on Tuesday from the Boston FBI. In a newly unsealed indictment, officials describe a five-year scheme by the lawmaker to use campaign funds for a slew of personal expenses, including golf club fees and gambling activities.

"If the allegations in the indictment are true, it is safe to say that Rep. Nangle has violated the public trust and especially the trust of constituents who donated to his campaign fund," US Attorney Andrew Lelling said at a press conference later Tuesday.

"This was not a momentary lapse of judgment or a technical foul," he added, "This was a systematic pattern of theft and fraud going back to at least 2014."

CNN has reached out to Nangle for comment on the allegations.
