A nationally recognized former coach at Austin-based Nitro Swimming faces a charge of indecency with a child, according to an arrest warrant affidavit.
Police have accused Tim O’Brien, who was named developmental coach of the year by USA Swimming in October 2015, of being involved in a relationship with an athlete he groomed from the age of 13 until she was an adult.
Earlier this year, USA Swimming in March banned O’Brien, 49, from coaching after the organization accused him of violating its code of conduct, which prohibits inappropriate sexual behavior or contact between coaches and swimmers.
In the affidavit filed Wednesday, the woman, now 26, told investigators that O’Brien exposed himself to her when she was 15 years old and that she would sleep naked with him when she was 16.
The woman said she lived with him when she was 21 but became frustrated with their relationship and moved out when she was 23, the affidavit said.
According to the affidavit, O’Brien had a phone conversation with Austin police detectives in which he admitted that the victim started going over to his apartment near Bull Creek when she was 16. But O’Brien said he only had a physical relationship with the woman when she was 17 or 18 years old.
He told police he believed the woman was “lashing out” because of the way the relationship ended, the affidavit said.
According to Swimming World magazine, O’Brien began coaching at Nitro Swimming in 2007 and helped the team win national titles at the Texas Age Group Swimming Championships. Nitro was named a Gold Medal Club by USA Swimming in 2015.
