A St. Albans man who may be armed is wanted on charges that he assaulted a woman at her home last weekend and later threatened her at her place of work, police said Thursday.

The man, Rusty A. Grignon, 34, is wanted on charges of domestic violence terrorizing, criminal threatening and terrorizing, according to a news release from Sheriff Dale Lancaster, of the Somerset County Sheriff’s Office.

The assaulted was reported to police about 12:30 a.m. Saturday at a residence on Hartland Road in St. Albans. Sheriff’s deputies met with a 35-year-old woman in Skowhegan after she had fled from her St. Albans residence.

The woman, who had injuries on her face, neck and arms, alleged that Grignon had assaulted her earlier that evening, according to the release. Deputies went to the St. Albans residence just before 3 a.m. but couldn’t find Grignon; and the woman’s car, a gray Hyundai Sonata, was gone. Police searched the area and asked other area law enforcement agencies to be on the lookout for the Grignon.

The next day, Sunday, Grignon allegedly confronted the woman at her place of work in Skowhegan, creating a disturbance in the workplace and threatening both the woman and another employee, according to the release. Grignon fled before Skowhegan police got there, the release said, and the agency has charges pending against him.

The sheriff’s office obtained an arrest warrant for Grignon on Monday in connection with the reported assault.

Police asked that anyone with information on Grignon’s whereabouts call the Somerset County Sheriff’s Office at 474-6386. The sheriff’s office recommended that the public not approach Grignon because “there is reason to believe that he may be armed,” according to the release.
