NAPANEE, Ont. - David Frost's sexual exploitation trial is hearing that the former hockey coach and agent used intimidation and aggression to motivate his teenage players.

A former Quinte Hawks player told a Napanee, Ont., court today that Frost punched one player for his poor play, threw a full water bottle at another, swung a stick at him and made others cry.

Jason Flick says Frost's only form of motivation was `intimidation.'

The Crown has said character witness testimony will prove Frost had total control over the teens he coached and was able to convince some to participate with him in sexual acts.

Frost has pleaded not guilty to four counts of sexual exploitation against two former players, who cannot be named.

His lawyers say Frost will deny that the acts took place.
