A Lynn man charged with trespassing could face more charges for allegedly soliciting money with a phony City of Boston permit, Suffolk County District Attorney Daniel F. Conley said.

MBTA Transit Police on Monday evening arrested GREGORY HARRISON (D.O.B. 8/2/65), a.k.a. CRAIG HARRISON, after a plainclothes officer working at the TD Garden saw him allegedly soliciting money from passersby for an unknown organization he claimed to represent. The officer recognized Harrison as having been stopped in the past for similar incidents, gave him a verbal trespass warning, and ordered him to leave the area of North Station and the TD Garden.

About an hour later at 8:00 p.m., the same plainclothes Transit Police officer spotted Harrison again at the building’s West Entrance and placed him under arrest. At the time he was taken into custody, Harrison was carrying what appeared to be a sponsor book bearing a fraudulent City of Boston seal. That item was seized as evidence for potential future proceedings.

Harrison was arraigned on a trespassing charge yesterday in the Boston Municipal Court. Based on his record – which includes an open forgery charge and numerous convictions for larceny, assault, and drug offenses – and representations that police and prosecutors would likely seek additional charges, Judge Eleanor Coe Sinnott set his bail at $1,500 cash and ordered him to return to court on April 11.

Harrison was represented yesterday by attorney Lisa Grant.
