A Dracut man is facing felony assault charges after allegedly holding a razor blade to a woman’s throat in a Dunkin’ Donuts parking lot.

Adam Giallanella, 31, was arraigned in Lowell District Court last week. He is charged with one count of assault and battery of a family or household member, three counts of assault and battery with a dangerous weapon, and one count of intimidating a witness.

About 4:40 p.m., on Friday, July 5, Tewksbury police responded to a report of an argument between a man and woman inside a 2006 Chevrolet Trailblazer parked outside Dunkin’ Donuts on Main Street. A witness told police he saw the defendant hold a razor blade to the victim’s throat, then flee after hearing sirens, according to a police report.

The woman, who was sitting in the grass by the time police arrived, told police she has known Giallanella for years and that they have dated in the past.

She also told police Giallanella was supposed to drive her to Tewksbury State Hospital, where she had a bed waiting for detoxification, according to a police report. She told police an argument occurred after Giallanella accused her of stealing his money, according to the report.

A witness reported seeing Giallanella allegedly throw an aluminum can at the woman after she exited the parked car, then hold a razor blade to her throat, according to the police report. When the witness tried to intervene, Giallanella allegedly turned to him with the blade, threatening him verbally, according to the police report.

The woman said she doesn’t believe the blade touched her neck, and she did not appear to have any injuries, police reported. She declined medical attention.

Police found and arrested Giallanella after searching in a direction pointed out by the witness.

Judge Stacey Fortes ordered Giallanella held on $2,000 cash bail, which he posted after his arraignment. He is scheduled to return to court Aug. 5 for a pretrial hearing.
