A former St. Augustine Prep ice hockey player who's now playing junior hockey in Canada was arrested and charged with sexual assault over the weekend, Sault Ste. Marie, Ontario, police said.

Mark Petaccio, 18, of Sicklerville, and two of his Sault Ste. Marie Soo Greyhounds teammates — Nick Cousins, 19, a top Philadelphia Flyers prospect, and Andrew Fritsch, 19 — were charged with sexual assault against a female known to them, according to a release from the police.

Petaccio, who played for St. Augustine during the 2009-10 season, was released on $1,500 bail on Monday, according to the Sault Star newspaper.

Canadian citizens Cousins and Fristch were released from custody after they were charged, but Petaccio was held over the weekend because of his U.S. citizenship, the paper reported.

According to police, the three are accused of sexually assaulting a woman at one of the players’ homes on Friday night.

All three are scheduled to return to court Oct. 1.

Petaccio, 6-foot-3, 190 pounds, has played in Canada the last three seasons — two with the Oshawa Generals and last season with the Greyhounds of the Ontario Hockey League.

He has 11 goals and six assists in 94 games over three years.

St. Augustine Prep hockey coach Tim Fingerhut said that Petaccio only spent his sophomore year at the school.

“When he was at St. Augustine, he was a fine student, a great hockey player and we had no disciplinary problems with him,” Fingerhut said on Tuesday.

Cousins, known for a feisty style of play, was selected by the Flyers in the third round of the 2011 draft.

The draft pick was acquired as part of the trade that sent Jeff Carter to Columbus last year.

The Flyers also acquired Jake Voracek and a first-round pick that turned out to be Sean Couturier.

“We are aware of the unfortunate situation involving Nick Cousins,” Flyers general manager Paul Holmgren said in a statement.

“Due to lack of information available to us, we will not comment at this time.”

The fifth-leading scorer in the Ontario Hockey League with 88 points (35 goals, 53 assists) last season, Cousins signed an entry-level contract with the Flyers in late March and played one game with the Adirondack Phantoms of the AHL.

In a statement, the Greyhounds said they would “continue to perform our duty in supporting the three members of our team as they go through the legal process,” while pledging to aid the police investigation.

“The strides made over each young man’s tenure here are what makes today’s situation so surprising,” the Greyhounds said in the statement.
