A youth ice skating coach from Torrance pleaded not guilty on Tuesday to charges of lewd acts with a minor.
Donald Vincent, 29, is accused of molesting an underage boy, and investigators have reason to suspect there may be additional victims.
Detectives with the LA County Sheriff's Department said the alleged abuse began when the boy was 12 and continued until he was 15. They said it took place at Vincent's home at the time in Hacienda Heights.
The boy is now 17.
At the courthouse in Pomona on Tuesday, prosecutors cited "another possible victim that (Vincent) has admitted to showering with..." and "hundreds of acts of sexual abuse over a four year period."
The court commissioner ordered Vincent to stay away from the alleged victim, if Vincent is able to make bail, which was increased to $1 million.
Vincent has been coaching in Southern California for seven years, in both group settings and one-on-one sessions, according to investigators. They said he's worked at a total of seven different ice rinks in LA, Riverside and Orange Counties.
"He's dangerous in the fact that we have one victim and we believe there's potentially other victims out there," said Lt. Carlos Marquez with the Special Victims Bureau at the sheriff's department.
One of the ice rinks, in Artesia, is billed as the home of figure skater Michelle Kwan.
"My client is a very well-respected ice skating coach," said Vincent's attorney, Bill Paparian. "He's never been in trouble before."
"He's entitled to the presumption of innocence, and we're going to litigate this case in court, not in the press," Paparian said.
