A Massachusetts State Police trooper was taken into custody over the weekend and now faces charges stemming from the alleged domestic abuse of his live-in girlfriend.

The trooper, whose name has not been made public, was charged with attempted strangulation, WCVB reported, adding that he was taken into custody on Saturday night at his Boxborough home.

The trooper’s girlfriend said that, on Saturday, he allegedly choked her and, at one point, had her in a chokehold, Fox 25 reported.

Investigators said to WCVB that the woman waited for the trooper to fall asleep before she left their home and notified authorities.

The trooper, who has been with the department for 14 years, was relieved of duty, and his department equipment and identification were taken, Fox 25 added.

Bail has been set at $500,000, and his arraignment was expected on Monday in Ayer District Court, according to WCVB. A hearing will also be held this week by state police to address the trooper’s future duty status.
