Philippoussis' father charged with child sex offences
The father of Australian tennis player Mark Philippoussis has been charged with allegedly molesting two children in the US. Vision: Channel Seven.
In a statement, Lieutenant Greg Rylaarsdam from the San Diego Sheriff's Department said Mr Philippoussis was arrested at his residence in the suburb of Mira Mesa by detectives from the Child Abuse Unit.
He faces multiple counts of "lewd and lascivious acts with two minor victims".

"Philippoussis works as a personal tennis coach in Northern San Diego County and the alleged molestation victims took tennis lessons from him," Lieutenant Rylaarsdam said.
"The investigation is ongoing at this time."
San Diego Sheriff Bill Gore said detectives were "looking for more victims in a molestation case in the North County".
Philippoussis was booked into San Diego Central Jail on suspicion of committing lewd and lascivious acts on a person under age 14 and having sex with a child age 10 or younger, CBS8 reported.

Nick Philippoussis coached Mark during his professional tennis career, during which Mark reached a career-high singles ranking of world No.8.
He won two Davis Cup titles with Australia, in 1999 and 2003.
He also reached the finals of the 1998 US Open and the 2003 Wimbledon tournament, but lost both matches.
In a Father's Day tribute on Instagram last September, Mark told his father: "Thank you for your support, guidance and always being there for me no matter what no questions asked. Love you."
"Love you to [sic] Son, Thanks," his father replied.
Although Nick had served as Mark's coach and mentor for much of his career, Mark opted to go it alone in 2006
Reports at the time suggested that Mark was no longer prepared for Nick's "interfering ways".
However, Mark said that suggestions the pair was estranged were invasive and wrong.
"Let me tell you, that stuff's ridiculous," Philippoussis said after losing to world No.2 Rafael Nadal in the first round at Flushing Meadows in 2006.
"It's frustrating when I hear that stuff because I'm a tennis player and athlete. Someone wants to write about my tennis, great. It's unfortunate when I have to read things about my personal life and my family.
"My dad's my dad. He's been there from the start. Without him, I wouldn't be where I am. There's nothing at all that's happened with my dad. I just needed to spend some time on my own.
"My dad's still there. I talk to him every day, even before matches. Nothing's changed. I just needed to have some time on my own, simple as that."
Less than two months after going their separate ways, Philippoussis broke a three-year title drought with success in Newport, Rhode Island.
"I think it was probably healthy for me, looking back now," he said.
"I think everyone just needs to spend a little bit of time on their own sometimes. I did that and I just kind of found myself where I was just on my own and training on my own and going to the gym.
"It's been a while since I was on the practice court by myself and I was on the court by myself, in the gym, and the first few days were tough. And then all of a sudden it just clicked, you know? I don't know. I just enjoyed it."
