LEWISTON – A 44-year-old Lewiston man is listed in serious condition at Central Maine Medical Center with a head wound after being beaten with an ice chopper.

Lewiston police say the attack took place Monday night and that Gary St. Hilaire may have been lured outside a Walnut Street bar by an individual or group who wanted to rob him.

Investigators said they had developed leads and were interviewing potential witnesses.

It was unclear where the ice chopper came from or why it was used to attack St. Hilaire. The implement is a long pole with a rigid section of metal at the end that’s used to break up ice.
