Bruce Rock, 49, a swimming coach for Mountain View High School, has been arrested on suspicion of five counts of sexual exploitation of a minor, a Tucson police spokesman said Thursday night.

Rock was booked into the Pima County jail. He is also  the owner and operator of the Pima Aquatic Club that rents pool time at Marana High School, said Sgt. Chris Widmer, a Tucson Police Department spokesman.

Widmer gave the following account in a news release: 

"In September, 2013, the Tucson Police Department’s Internet Crimes Against Children / SORT Unit received a tip from the National Center for Missing and Exploited Children in reference to an unknown person uploading child pornography to a social media website. An investigation revealed that the materials were uploaded from a residence in the 8200 block of North Willow Blossom Drive. On September 26th, a search warrant was served at the residence. Evidence was located that implicated a resident from the home as being involved in the uploading of child pornography. The suspect was identified as Bruce Rock, 49."

Police did not release a booking photo.
