WEYMOUTH — Four masked and hooded Boston juveniles, aged 16 and 17, were arrested at a luxury Weymouth apartment complex early Sunday morning after the town's automated FLOCK camera network flagged a stolen vehicle on Washington Street at 4 a.m., according to the Weymouth Police Department.

Officers responded to the FLOCK alert and located the stolen car parked at the Hanover Weymouth, a high-end apartment complex at 1325 Washington Street. A second stolen vehicle was found nearby. As officers moved through the complex, they observed four individuals wearing dark clothing, masks, and hoods peering into parked cars. Two of the suspects fled a short distance before all four were detained.

Investigators found six vehicles at the complex that had been broken into or tampered with and recovered property believed stolen from them — some of it in the area where the suspects had been observed, and some on the suspects themselves at the time of the arrests. Officers contacted several vehicle owners, who confirmed items had been taken from their cars.

All four juveniles gave home addresses in Mattapan, Dorchester, and Hyde Park — three of Boston's largest neighborhoods, roughly 20 miles from the complex they had chosen to hit. They were transported to Weymouth Police Headquarters and booked. Each faces:

Eleven charges each. In one night. Off a single automated camera alert.

FLOCK Safety cameras are automated license-plate readers that flag stolen or wanted vehicles in real time and push the alerts directly to contracted police departments. They are the technology every progressive city council in Massachusetts has spent the past twelve months trying to disable.

Cambridge halted its FLOCK contract in October 2025 after the City Council voted to end the program over privacy and federal-data-sharing concerns. The city officially cancelled the contract in December.

Brookline, Natick, and Watertown all successfully pushed back against FLOCK during pilot or installation phases.

Boston, Cambridge, and Somerville each have surveillance-oversight ordinances designed to slow police adoption of technologies like FLOCK.

Weymouth kept its FLOCK network.

On Sunday morning at 4 a.m., that network flagged a stolen car on Washington Street. Within minutes, officers were at the Hanover Weymouth. Within the hour, four Boston juveniles were in custody, two stolen vehicles were recovered, six break-ins were cleared, and stolen property including a credit card was returned to its owners.

The FLOCK cameras the ACLU of Massachusetts and Digital Fourth want disabled did exactly the job they were installed to do.

All defendants are presumed innocent unless and until proven guilty in a court of law.
