NAPANEE, Ont. - A judge in Napanee, Ont., has dismissed a bid by former hockey coach and player agent David Frost to have sex-related charges dismissed.

Frost faces six charges of sexual exploitation involving four teenagers dating from his days as a hockey coach in Deseronto, Ont., in the early 1990s.

The ruling was issued Monday against Frost, who has denied all charges and will next appear in court on August 25.

Frost was initially charged with six other sex-related offences but they were dropped in March 2007 due to insufficient evidence.

His trial is scheduled to begin in Napanee on October 14.

Frost is also facing trial next April on fraud charges over the alleged illegal use of a credit card belonging to jailed St. Louis player Mike Danton.
