“In the overnight hours both Mountainside and Westfield have experienced criminal activity involving actors entering open and unlocked doors of residential homes in the surrounding area,” the police alert said.

Videos posted to the social media site Ring.com’s Neighbors App Friday show security footage of the suspect activity on Garfield Avenue, Grant Avenue and in the area of Wychwood in Westfield.

Westfield police reported three attempted home break-ins on Cherry Lane, the 1000 block of Wychwood Road and the 800 block of Grant Avenue.

Entering through an unlocked rear door, a burglar crept into a home in the 500 block of Wychwood Road, then stole goods, police said.

An unknown suspect attempted to burglarize a car on Cherry lane, and a person succeeded in burglarizing a car in the 800 block of Grant Avenue, police said.

The burglars did not “forcibly enter” any of the residences, police said, citing their review of Ring videos submitted by residents.

“The Westfield Police Department takes this situation very seriously and will be employing all appropriate measures to address it, including enhanced patrolling and surveillance,” the police statement said.

Break-ins to unlocked cars in Westfield have been an ongoing issue in recent months. 

Westfield last saw a rash of home break-ins in 2018, during which suspects snuck into unlocked houses then stole cash, credit cards and other valuables while the residents were sleeping.
