SCHERERVILLE, Ind. (AP) — Indiana State Police and excise officers have raided two northwestern Indiana Mexican restaurants as part of an investigation that involves other restaurants in central Indiana.

The Times reports the raids Monday at La Carreta restaurants in Merrillville and Schererville were part of a larger investigation that targeted El Rodeo restaurants in Indianapolis, Lafayette, West Lafayette and Richmond.

Marion County Prosecutor Terry Curry says search warrants were served at numerous locations as part of an ongoing investigation but his office isn't commenting any further. A spokeswoman says the Marion County and Tippecanoe County prosecutors' offices initiated the investigation.

The Times says the restaurants are owned by Arnulfo Gonzalez. He doesn't have a published home telephone number.
