Hockey Manitoba is investigating after underage players toasted a championship win with alcohol.

Peter Woods, executive director of Hockey Manitoba, confirmed the probe to CBC News Wednesday.

He said eight 13- and 14-year-old players on the Neepawa Bantams were served alcohol at the Yellowhead Arena on March 7. Woods said he didn't know who served the alcohol or what type it was.

"It's certainly … illegal," he said.

The incident came to light after concerned parents contacted the editor of a local newspaper, the Neepawa Banner, and one sent an unsigned letter to the editor.

The Banner reported the story on March 28.

So far the Neepawa Minor Hockey Association says it is in the dark as to who broke the rules and the law. The legal drinking age in Manitoba is 18.

The president of the association confirmed to CBC the incident occurred but declined to be interviewed.

He said apology letters had been sent to parents. 

RCMP say anyone supplying booze to minors is subject to a $1,000 fine per child. Staff Sgt. Eric Davidson told the Banner his officers couldn't take action because there was no evidence.
