The Somerville Police arrested a suspect on Monday night for the armed robbery of a Tufts graduate student last Friday.
Police attained a warrant to arrest Robert Galatis, 29, and confronted him at his house at 182 Powderhouse Blvd., according to Sargeant Robert McCarthy of the Tufts University Police Department (TUPD).
"Somerville Police made an arrest based on information [gathered from] working with Tufts, Medford and Somerville Police," McCarthy said.
McCarthy said Galatis matches the suspect description that TUPD e-mailed to the student body on Friday: a white male with a crew cut, approximately 5'9" tall.
Max Kardon, a student at the Fletcher School of Law and Diplomacy, was robbed at knifepoint at about 1 a.m. on Friday morning. He and his friend had stepped in to help a female undergraduate who was being harassed by the assailant.
Surveillance cameras at a local CVS Pharmacy and a Dunkin' Donuts caught footage of a man using Kardon's credit card shortly after the incident Friday morning. In the footage, the man is accompanied by a female. Also, Kardon saw a red Ford Taurus pick up the attacker directly after the armed robbery.
The Somerville Police have yet to identify or arrest the woman in the video, McCarthy said.
