CAMBRIDGE, Mass. (AP) – A state police trooper was indicted Thursday on charges he repeatedly sexually assaulted a woman in a state-owned building while he was on duty.

Daniel Grant, 42, of Holbrook, a 17-year veteran trooper, is charged with three counts of rape.

Authorities say Grant, while on duty in Cambridge on Jan. 20, approached a parked car. A 26-year-old victim and another man were in the car. Grant allegedly offered the man a small amount of cash and told him to leave, then told the woman to follow him in her car.

In his cruiser, he led the woman to a state-owned building in Cambridge, where he repeatedly sexually assaulted her, according to the indictment.

Grant, through his lawyer, Timothy Burke, denied the charges.

“It’s important to point out the grand jury, the first time this case was presented, voted not to charge him,” Burke said.

The Middlesex District Attorney’s office refused to disclose further information prior Grant’s arraignment, scheduled for April 7 in superior court.

Grant was suspended from his job.

“The department is aware of the indictment and the seriousness of the alleged complaint made against Trooper Grant,” State Police spokeswoman Lt. Sharon Costine said, reading from a prepared statement. “The department has cooperated fully with the Middlesex District Attorney’s Office and will continue to do so as the judicial process continues.”
