INDIANAPOLIS - The Marion County Health Department says more than 160 people have claimed they became ill after eating at an Olive Garden restaurant in Indianapolis last weekend.

A health department spokesman says they're trying to isolate the cause and have found no health code violations at the restaurant on the city's north side. Health officials are collecting leftover food and stool samples from those who were stricken in an effort to pinpoint the source of the illness.

A spokesman for Olive Garden was not immediately available for comment.
