The former head of the State Police Association of Massachusetts and a lobbyist for the union were arrested Wednesday.

The U.S. Attorney’s Office announced their arrests early Wednesday. FBI officials said Dana Pullman, the former head of the State Police Association of Massachusetts, and Anne Lynch, a Beacon Hill lobbyist, were arrested at their homes in Worcester and Hull, respectively.

Pullman, a 31-year veteran of the state police, resigned as president of the organization in September, citing personal reasons. He served as treasurer for the police union from approximately 2008 until 2012, when he became president of the organization.

He resigned from state police weeks later, amid an ongoing investigation by federal authorities into alleged misuse of union funds for personal benefit. The organization justified a denial of records requested by MassLive in the fall citing the ongoing investigation.

“The documents you have requested are the subject of/ connected to an active and ongoing investigation by federal officials,” State Police legal counsel Siobhan E. Kelly wrote. “Those officials have confirmed to the Department that disclosure of the records at issue would jeopardize their investigation.”

On the day of Pullman’s resignation, State Police Col. Kerry Gilpin sent the union a letter saying the department would begin cracking down on allegedly improper uses of publicly funded union business leave.

Pullman received just over $108,000 in pay last year, including $78,410 in base pay, $28,578 in buyout pay and $1,075 in pay categorized by the state as “other.” He did not receive overtime pay for the year.

He took in another $71,000 annually from the union.
