Man wanted for armed robberies arrested in Dorchester

A 53-year-old man who was a suspect in several recent armed robberies in Somerville was arrested Friday morning in Dorchester, police said.

Officers from the Boston Police Fugitive Unit, Massachusetts State Police, and the Somerville Police Department found Lorne Harrison of Mattapan in the area of 31 Lonsdale St. in Dorchester around 11 a.m., Boston police said in a statement.

Harrison was wanted on a warrant out of Somerville District Court for armed robbery, as well as for violating the terms of his lifetime parole. He allegedly used a gun in multiple robbery attempts in the Somerville area, police said.


Harrison was expected to be arraigned in federal court in Boston, police said.

In a statement, Somerville police praised the work of one officer, Ariel Collazo, in identifying Harrison, whom police said committed an armed robbery at the Assembly Row Kay Jewelers on Aug. 30.

According to the statement, Harrison walked into the jewelry store with a ball cap pulled down low and dark sunglasses.

Somerville police said Harrison walked over to a clerk, handed him a bag, and said, “Fill it.”

When the clerk didn’t immediately respond, Harrison pointed a handgun at him, authorities said.


The clerk filled the bag with jewelry, and then Harrison ordered him to ground and fled. Despite police responding to search the area, Harrison was able to escape, according to authorities.

The quality of the video from the jewelry store was not good, according to police.

Collazo contacted a security manager at Assembly Row, who helped track Harrison’s movements throughout the outdoor shopping center, according to police. Collazo tracked Harrison back to a T.J. Maxx, according to police. The store had captured surveillance footage of Harrison without his disguise, police said.

Collazo was then able to map out Harrison’s escape route via the MBTA, according to police. A clear photo of Harrison, his MBTA escape route, and the distribution of a crime bulletin to regional law enforcement partners played a major role in his capture, police said.

“Thanks to Ariel’s dogged work and keen instincts, a dangerous individual will go back to serving the rest of his life behind bars,” said Somerville police in a statement.


For his efforts, Collazo will be presented with Somerville’s “Beyond the Call of Duty Award” on Sept. 13.
