Police: Probation GPS Monitor Put Suspect At Scene Of Indecent Assault In Arlington

ARLINGTON (CBS) – A GPS monitor helped police identify and track down a 21-year-old man suspected of indecently assaulting a teenager on Tuesday in Arlington, officials said.

Officers say the victim, a 14-year-old student, was walking home from school on Summer Street just past Cutter Mill Road when someone came up and committed the alleged assault.

The victim managed to provide police with a good description of the suspect, which was made public.

The state's Chief Probation Officer Joseph Jackson Jr. saw the sketch and reached out to Arlington police after realizing that Patrick Barry of Medford, who was previously charged armed sexual assault and attempted rape on two women in Mission Hill, fit the suspect description.

That prompted Arlington police to take a look at the GPS log at the Boston Regional Intelligence Center, which they say placed Barry in the exact spot of the assault and battery at the exact time of the alleged incident.

Barry was arrested at his home and charged with indecent assault and battery on a child over 14 years of age. He is being held at the Arlington police station until his arraignment on Friday.

Police say he could face additional charges.
