A man faces a pair of assault-related charges after he allegedly struck another man in the head with a hockey stick during a weekend game, police say.

The Middlesex County OPP say the alleged incident occurred Sunday at a hockey arena in Thames Centre, near London. It involved two men in their 30s.

In a news release, police say an investigation has determined that "the accused swung his stick at the victim, intentionally, with force, and unrelated to the play."

The injured man, who lives in London, went to hospital after being struck. He suffered serious, but non-life threatening injuries, police say.

A 36-year-old man from Thames Centre faces charges of assault with a weapon and assault causing bodily harm.

The accused is due to appear in court next month. The charges against him have not been proven in court.

Two months ago, the same OPP detachment reported an assault charge being laid in a different hockey game involving a young person.

"Our stance would be that it's happened too many times," OPP Const. Liz Melvin told CBC News in a telephone interview on Wednesday afternoon. "We don't want to see this kind of behaviour in any way, shape or form."

Melvin said it is "disturbing" to see these kinds of incidents taking place on the ice.

In both cases, police warned the public to "conduct themselves properly" on ice, noting that criminal charges will be laid when appropriate.
