State Police are investigating a series of break-ins in Monroe County.

Troopers said seven East Stroudsburg businesses were hit on Monday night.

Businesses on Milford Street said this isn't the first time they've been targeted.

"This is the third time, in about two months," said Mahagany Cohen, a stylist at Divas II Salon.

Divas II Salon said the intruder walked out with hundreds of dollars in the first incident, and $30 in the second. The salon no longer leaves cash overnight.

"Even though we put signs in the door saying there's no money here, they are still doing it," Cohen said.

The salon also beefed up its security measures in hopes of preventing a repeat

"After the first one, we put some cameras inside the salon. We also have an alarm system in the salon. We've been leaving the lights on every night," Cohen said.

Cohen said the intruder walked away empty handed on Monday night.

In surveillance video from Monday night, a person is seen grabbing the cash register from the salon before heading out the door. Workers said the intruder used a rock to break open the front glass door before entering.

"I believe it's the same person. Every time they take the register with them, we find it in the same spot," Cohen said.

Cohen said the salon is considering additional measures to prevent it from happening a fourth time.

"We are thinking about putting some gates, this way to stop this from happening," Cohen said.

Just down the road, Bilal's Halal Meat Market was also broken into. The meat market was broken into in August.

"After the first time, we leave the cash register open to show the crook there's no cash here," said Abdul Shaheed, a butcher.

Shaheed said this time, there was no money for the crook to take. However, the business had to fork out $600 to repair its front door.

Shaheed said the business is considering a security system, but also plans on checking up randomly.

"We may be having random checks of the store. Each of the workers, and the boss swinging by to see if anything is going on," Shaheed said.

Anyone with information is asked to contact State Police in Swiftwater.
