WESTFIELD, NJ – A slew of vehicles were broken into and one stolen Saturday night into Sunday, police said.

An unknown thief stole a 1998 Toyota Corolla from a driveway in the 600 block of West Broad Street in one of the 10 vehicle break-ins reported to police between 5:35 a.m. and 12:18 p.m. on Sunday, police reports show.

Six of the break-ins occurred on Scotch Plains Avenue, police said. Additional break-ins occurred on Shadowlawn Drive, Austin Street and West Broad Street, police said.

In at least five of the instances, police reports show, the burglar or burglars broke into unlocked vehicles. In two of the cases, the residents reported nothing stolen. But in most cases, the burglars either stole cash, personal items or both.

The weekend break-ins follow an attempted break-in on May 11, police said.

In that case, a resident of Manchester Drive told police two men attempted to burglarize his vehicle while it was parked and locked, but the suspected burglars’ efforts were thwarted and they drove away in a dark-colored sedan, police said.

While vehicle break-ins are hardly a new problem for Westfield, the 10 incidents in one evening mark a spike in criminal activity.

In February, police reported five vehicles broken into on Tremont and Kimball avenues. Earlier that month, police had chased a U-Haul, which had been seen in the area where four vehicles were entered on Wyoming Street, Florida Street and Belmar Place.

Last year, Westfield police joined a national campaign, called #9PMRoutine, to remind the public to lock up at night.
