A Massachusetts man is accused of kidnapping and assaulting a woman he met on Tinder, threatening to kill her and her child if she went to the cops, authorities said.

Peter Bozier, 28, was arrested Tuesday during a traffic stop in Sudbury after the victim told investigators she was severely beaten and strangled while being held against her will at Bozier’s home, police said.

The victim said the harrowing ordeal began a day earlier, police spokesman Lt. Robert Grady told the MetroWest Daily News.

Grady said the woman managed to “release herself from the situation” and then went to a hospital in Burlington, where hospital staffers contacted police, the newspaper reported.

Police said Bozier, of Sudbury, threatened to kill the woman and her child as a way to intimidate her from reporting what allegedly happened to authorities.

The Middlesex district attorney’s office said she had been visiting Bozier after connecting with him on the dating app a week earlier, the Boston Globe reported.

Bozier was later taken into custody while driving without a license, prosecutors said. He was initially cooperative, but then turned “belligerent” while being booked at a police station, leaving several officers with scrapes and cuts during multiple altercations, police said.

Bozier, who had a small cut on his finger, then complained of other medical ailments, leading him to be taken to a hospital twice for treatment before he was cleared by staffers there, police said.

Bozier was arraigned Wednesday on charges including kidnapping, strangulation, assault and battery and intimidation of a witness. He was ordered held without bail pending a dangerous hearing next week, authorities said. It’s unclear if he’s hired an attorney.

A message seeking comment early Friday from Tinder was not immediately returned.
