FERNDALE - After a string of nine similar burglaries, Ferndale police are asking downtown business owners to be on the lookout.

Since early November, burglars have struck eight businesses in downtown Ferndale, in the 2000 block of Main Street, the 2000 block of Vista Drive and the 2200 block of Douglas Road. One store was struck twice. The latest heist was reported this week.

Police have a few good leads and a possible suspect, but don't have probable cause for an arrest, said Lt. Bill Hatchett. Officers aren't even sure if the same suspect - or suspects - is involved in each burglary.

But a few things line up.

Each time, glass doors were shattered in plain view of the main road. Each time, the suspect rifled through the register looking for cash. None of the businesses had alarms. All were burglarized under cover of darkness.

Sometimes up to $200 was taken, sometimes the burglar left empty-handed. The cost of the shattered glass, Hatchett noted, amounts to far more than the value of the cash.

Police declined to release the names of the shops. Hatchett said it's especially frustrating because locally owned business owners were victimized.

Ala Enayati, owner of the 7-Eleven on Main Street, said the security cameras flanking his store - a dozen of them - seem to have warded off any burglars. The minimart hasn't been hit in the 17 years he's worked there.

"Not yet," Enayati said.

The City of Ferndale sent out these tips:

• Don't leave money in your business overnight.

• Post a sign saying no money is onsite.

• Leave lights on near doorways at night.

• Consider getting security cameras.

• Consider getting an alarm system.

And if you see anything suspicious, call 911.
