Police said they seized $240,000 from more than a dozen DeKalb County businesses during illegal gambling raids Thursday.

Authorities raided 14 Chamblee businesses, including convenience stores, check cashing establishments, laundromats and a pool hall, according to a news release from the Chamblee Police Department.

Eleven individuals were arrested and identified as employees, and two people were arrested for outstanding warrants, police said. Their names were not immediately released.

The raids were the result of a three-month undercover investigation into gambling with illegal game machines, according to police.

Chamblee authorities were assisted by officers from the Dunwoody and Doraville police departments.
