After a run of vehicle break-ins and thefts this week, Arlington police are warning residents that some thieves are barely breaking a sweat. Many of the reported incidents involved unlocked cars or keys left inside, giving people easy access to parked vehicles in residential neighborhoods.

The advisory followed social media chatter and neighborhood reports of people seen opening doors of parked cars around town. In several cases, residents said the suspects simply tried door handles until they found vehicles that were unlocked.

The Arlington Police Department put out a town-wide notice on Thursday, urging residents to take “extra precautions following a recent increase in motor vehicle thefts and motor vehicle break-ins throughout the community,” according to Town of Arlington. The release reminds people to lock their vehicles every time, never leave keys or spare fobs inside, remove valuables from plain sight, and fully close windows and sunroofs. Residents are also asked to report suspicious activity to 781-643-1212 or call 911.

Police recommendations

“These simple steps can significantly reduce the likelihood of theft and help keep our neighborhoods safe,” the alert noted, according to the town release. Police stressed that basic habits like locking up and taking keys go a long way, even if they seem obvious.

Officers also said they appreciate tips, calls, and home-security footage from residents as they dig into the recent reports. That kind of video, they said, can help them piece together timelines and patterns as the investigation continues.

Neighbors posted video in Morningside Heights

On June 1 and June 2, neighborhood social media posts circulated security-camera clips that appear to show a group of young males walking through the Morningside Heights area and opening the doors of parked vehicles, according to Your Arlington. In the comments, residents swapped stories, traded video, and asked neighbors to stay alert.

Those posts helped build momentum for the town advisory, as more people came forward with their own footage and accounts of similar late-night prowling.

How thieves exploit unlocked cars

Leaving a car unlocked or stashing keys and fobs inside effectively turns a quick walk-by into a quick getaway. In some cases, criminals use electronic “relay” attacks that amplify the signal from a keyless fob so a vehicle can be opened and started without any sign of forced entry. A recent review of smart-vehicle security describes how those relay attacks work and notes that law enforcement and security experts recommend storing fobs away from doors and windows or in signal-blocking pouches to cut the risk, according to ScienceDirect.

Arlington police say they are actively investigating the incidents and again urge anyone with video, information, or concerns to contact the department at 781-643-1212, or call 911 in an emergency, according to Town of Arlington. Officials say following the straightforward precautions in the alert can significantly reduce the odds of becoming the next victim.
