The Los Angeles Police Department executed a search warrant at Gene Simmons' house on Thursday, police said.
"No one in the the Simmons family is a suspect in this investigation," police said in a statement.
They would not discuss the ongoing investigation.
A representative for Simmons said in a statement that members of the LAPD visited Simmons and his wife at their home to discuss a crime that may have occurred on their property last year while Simmons was away on tour with KISS.
"Neither Mr. Simmons nor any member of his family is a Person Of Interest in the investigation and they are cooperating fully with the investigation," the statement said. "At this time, the police have requested that Mr. Simmons and his family not discuss the investigation publicly so as not to compromise it."
