An undercover sting by the Petaluma and Santa Rosa police departments Wednesday netted a Santa Rosa resident who was allegedly driving on a suspended license, according to a joint statement released by the departments.

The operation took place at the Sonoma County Courthouse, where officers from both departments targeted suspected DUI drivers whose licenses were suspended and/or revoked or who were driving without a license.

Police said they identified about 15 suspects who were told by the courts they weren't permitted to drive. Each suspect was followed out to their cars to ensure they were complying with the law.

Steven Delange, 53, of Santa Rosa, was the only suspect who got behind the wheel and drove himself away from the courthouse, police said. Delange, who was driving on a suspended license, was cited and his vehicle impounded, according to police.

The operation was funded by a grant from the California Office of Traffic Safety through the National Highway Traffic Safety Administration.
