A 41-year-old Lowell, Massachusetts man is facing armed robbery charges after he was nabbed walking away from a Bridge Street convenience store he had just robbed at knifepoint, police said.
Michael J. Silva, no known address, was arrested about 4 p.m. on Albion Street, where officer Stephen Morrill chased him after spotting him on West Fifth Street, police said.
Morrill was on his way to a reported armed robbery at Store 24, 494 Bridge St., when he spotted Silva carrying something blue and saw several people pointing at him.
The blue item turned out to be a lottery machine from the store, police said.
Silva held the store up by walking in, going behind the counter, and lifting a pair of large knives above his head while saying something incoherent, police said.
The clerk ran from the store and called police.
