A judge in Napanee, Ont., on Monday dismissed a bid by former hockey coach and player agent David Frost to have sex-related charges against him dropped.

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

Frost, 40, will next appear in court on Aug. 25, and his trial is scheduled to begin in Napanee on Oct. 14. He 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.

Danton, a Brampton, Ont., native and former St. Louis Blues forward, was sentenced to seven and a half years in a U.S. federal prison in November 2004 for plotting to have Frost killed.

Frost, who resigned as an NHL agent in December 2005, has denied he was the intended target of the plot.

In spite of his conviction, Danton has continued to defend Frost.

A resident of Battersea, Ont., Frost was arrested in August 2006 following a two-year investigation by the Ontario Provincial Police.

He was charged with 12 counts of sexual exploitation and one count of assault of four males and three females. Police said they were between the ages of 14 and 16 at the time of the alleged assaults, which reportedly took place between 1995 and 2001 in the Deseronto and Napanee area of eastern Ontario.

In March 2007, the Crown dropped six sex exploitation charges and one assault charge against Frost, citing insufficient evidence.
