BOSTON – Police said Friday that they charged Mike Milbury, the former Boston Bruins player and coach, with assaulting a 12-year-old Pee Wee hockey player who was arguing with his son.

Milbury coached the Maine Mariners from 1987-89.

Brookline (Mass.) police Capt. Tom Keaveney said Milbury, an assistant coach on his son’s team, allegedly grabbed, threatened and shook the opposing player as the teams were shooting around following a Dec. 9 game at a town-owned rink. The boy wasn’t hurt, Keaveney said.

Milbury, 59, of Needham, Mass., will be summoned to court to face misdemeanor charges, including assault and battery on a 12-year-old, threats to commit a crime and disorderly conduct, he said. Keaveney said police have video evidence of the alleged attack.

But Milbury denied an assault “of any kind,” in a statement from his lawyer.

“He simply intervened in an altercation between his son and an opposing player,” the statement said. “No one was struck, no one was injured and no one was threatened.”

Milbury, a defenseman, played parts of 12 seasons with the Bruins and later served as coach, leading the team to the Stanley Cup finals in 1990, where they lost to Edmonton. He also was coach and general manager of the New York Islanders.

Milbury was well-known as a player for a 1979 incident when he brawled in the stands in New York with fans who grabbed some teammates’ sticks, whacking one fan in the leg with his own shoe.

Milbury is now an NHL analyst with NBC Sports, which said he had been taken off the air.

“We both came to the conclusion that he should remain off the air while focusing on his affairs,” NBC Sports said in a statement.

Keaveney said police learned about the alleged assault from a parent who wasn’t there but heard about it afterward.

He said officers interviewed witnesses, including the alleged victim, before bringing charges.
