Gene Simmons' home was searched by the Los Angeles Police Department's Internet Crimes Against Children Task Force on Thursday (20.08.15).
Officials have insisted the 65-year-old rock star and his family are not suspects in the case, but have refused to reveal who the target of their investigation actually is, the Los Angeles Times reports.
Officer Mike Lopez explained that the police went to the home of the Kiss guitarist on Thursday morning with a warrant to search the property.
Meanwhile, a spokesperson for the Simmons family has told NBC that the police wanted to discuss a crime that could have occurred at Simmons' residence in 2014 while he was away on tour.
A statement read: ''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.''
Meanwhile, Simmons' wife, actress Shannon Tweed, has taken to Twitter to thank friends and fans for their support.
She wrote: ''Thanks for your support. We couldn't be more horrified that someone used our residence for such heinous crimes. Law enforcement is on it.''
