YORK COUNTY, S.C. -- It was a busy morning for thieves in York County.

Investigators say they went on a stealing spree, breaking into 15 cars in one neighborhood early Friday morning.

Deputies say it was a resident of the subdivision that called 911 after witnessing several people going through cars. Officers responded to the community just before 4 a.m. and quickly arrested 20-year-old William Brock.

Several hours later, they made three additional arrests. Jacquelyn Page, 21, 17-year-old Courtney Page and 18-year-old Austin Alexander were all are charged in connection these break-ins.

"We just moved here from California, so we're new to this so it is a little bit of a surprise because we're thinking of this as being a less crime prone area," said Ken Cooper.

It wasn't just this neighborhood hit by thieves. The York County Sheriff's Department released a video earlier this week from an April 27 incident. In the video, four crooks can be seen going into unlocked vehicles stealing cash and electronics at the Adnah Hills Mobile Homes.

It isn't clear if the four in custody now are responsible for this incident. Also, there have been at least 10 more incidents of car break-ins and thefts in York County since Tuesday. According to one incident report, thieves stole a handgun from a center console of an unlocked car. The vehicle was parked in a driveway of a subdivision less than a mile from Friday morning's crime spree.

"That's scary, that's really scary," said Orville Waller who lives a few doors down.

The problem goes beyond York County. The Lincoln County Sheriff's Department alerted residents of a rash of car break-ins that occurred on May 4 on Old Plank Road in Stanley and Mundy Road in Denver.

They also say there were additional incidents May 10 in the area of Club Drive off Highway 73 in Stanly.

"It means we're going to lock our cars," Cooper declared.
