A 28-year-old New Hampshire man is facing charges after he allegedly threatened a conductor with a knife on the Haverhill commuter rail line last week.

Eric Foster of Plaistow, N.H., is to be arraigned today in Haverhill District Court for assault with a dangerous weapon, MBTA Transit Police said in a statement.

Foster allegedly threatened the conductor at about 9:50 p.m. Friday after the conductor woke him up as Haverhill, the last stop on the line, came up. He fled and Transit Police and Haverhill police were unable to locate him, Transit Police said.

On Monday, Foster allegedly attempted to board a Haverhill-bound train at North Station at about 8:30 p.m. The same conductor was working on that train. He refused to let Foster board and called Transit Police. Foster again allegedly threatened the conductor. He fled before Transit Police arrived.

But after a search, officers found him inside a 7-Eleven store on Causeway Street, Transit Police said.
