The girls swim coach at Mountain View High School was fired Friday, the school’s principal said in a letter sent to parents.
Principal Patricia Cadigan wrote the firing was in response to the arrest Thursday of Bruce Rock.
Rock, 49, is facing five counts of sexual exploitation of a minor.
“I want to assure you that there is no indication that the charges leading to Mr. Rock’s arrest involve a MUSD (Marana Unified School District) student or Mountain View High School,” wrote Cadigan.
She informed parents that Justin Madison will be head coach for the girls swim team.
A Tucson Police Department investigation and the execution of a search warrant at Rock’s home implicated Rock in uploading child pornography to a social-media website, said Sgt. Chris Widmer, a police spokesman.
The tip that led police to investigate came from the National Center for Missing and Exploited Children, Widmer said.
Rock lives in the 8200 block of North Willow Blossom Drive. The neighborhood is south of West Cortaro Farms Road and east of Interstate 10.
Rock also is the owner and operator of the Pima Aquatic Club. It rented pool time at Marana High.
According to the club’s website, Rock moved to Tucson in 2004 and started coaching the county league team at Northwest YMCA in 2007, building it to a USA swim team. He has coached many years as a USA head coach and at Mountain View, the website said.
