WILMINGTON (CBS) ? Players and fans witnessed a frightening incident at the Boston Bruins practice in Wilmington Thursday morning.

A fan collapsed in the stands at Ristuccia Memorial Arena.

According to the Wilmington Patch, the man lost consciousness after having a seizure and was rescued by police who used an Automated Emergency Defibrillator (AED) that was hanging outside the Bruins locker room.

“He had a heart attack,” WBZ NewsRadio 1030′s Tom Cuddy reported from the arena.  Cuddy said the man happened to be sitting near an EMT from Harvard, who rushed in to help, along with an off-duty Wilmington police officer.

“This man was dead,” Cuddy said, until his rescuers revived him.

The Bruins medical staff also helped in the resuscitation.

A team spokesperson told WBZ-TV players “took a knee” on the ice during the rescue.  The unidentified man was taken to the hospital and practice resumed.

The Bruins issued this short statement on Twitter after the incident:
