COLLIER COUNTY, Fla.- Ivan Zurita, General Manager of Alberto's on 5th Avenue South has a warning for other businesses.

"Just be careful. Unfortunately this has been our turn, so I hope nobody make the same mistake."

The mistake started when someone called the restaurant claiming to be FP&L. The caller threatened to shut off the power, unless the business paid $1500.

"They knew everything about our accounts, we have 3 accounts with FPL , they knew all the numbers."

Zurita followed their demands, buying pre-paid cards known as Green Dot money packs.

"Then they called on Saturday to pay 1600 for May."

In the end, the restaurant paid the crooks twice, more than three thousand dollars total. The number in question has an Illinois area code. WINK News called several times, but each time the call went straight to voicemail.

Naples Police Lieutenant John Barkley tells WINK News, this crime may be connected to another incident just days ago at Sea Salt on 3rd Street South. Same number, same deal. The restaurant paid $1,500 out of fear that it's power would be shut off.

"It's a life lesson. Iit's a little bit of an expensive lesson from now on we need to take care of all that."
