Australian tennis coach Nick Philippoussis has pleaded not guilty to 14 charges in relation to child molestation.
Philippoussis, father of retired Australian tennis star Mark, was arrested at his home in San Diego on Tuesday.
The 68-year-old was arrested on suspicion of sexually abusing two nine-year-old girls that he had been privately coaching.
It was alleged Philippoussis abused the girls in different San Diego locations, including his home, his car and a tennis complex.
If convicted, he faces a maximum jail sentence of 21 years to life.
However, his lawyer Ryan Tegnelia said his client was innocent and would fight the charges.
