Police in LA investigating online crimes against children have searched the home of KISS bassist Gene Simmons, however authorities have stressed that neither he nor his family are suspects.

A spokesman for the Los Angeles Police Department said the warrant was served on Thursday at the house in Benedict Canyon near Beverly Hills.

"No members of the Simmons family are suspects in the case and were extremely cooperative," he said.

A representative for Simmons released a statement which read: "Today (Aug. 20, 2015) members of the Los Angeles Police Department visited Mr. And Mrs. Simmons at their home to discuss a crime that may have occurred on their property last year while Mr. Simmons was away on tour with KISS."

It continued: "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. At this time, the police have requested that Mr. Simmons and his family not discuss the investigation publicly so as not to compromise it."

In a tweet, Simmons' wife Shannon Tweed thanked people for their support and said they were "horrified" crimes may have been committed at the house.

"Law enforcement is on it," she wrote.
