A Westbrook man is in custody and police are seeking another suspect following an assault and robbery in Gray early Wednesday morning.

The Cumberland County Sheriff’s Office responded to North Raymond Road at 1:20 a.m. for a report that a 20-year-old man had been beaten up outside his home by a group of suspects who then stole several items from his house, police said.

The victim was treated at a local hospital for minor injuries, the sheriff’s office said.

Deputies identified suspects, and then a vehicle matching one that left the scene was found in Westbrook. One occupant, Sam Kalmach, 19, of 33 Foster St. in Westbrook, was arrested and charged with robbery, aggravated assault and burglary — all felonies. He is being held on $2,000 bail at Cumberland County Jail.

The sheriff’s office said it is looking for Matthew Kalmach, 21, of Portland, in connection with the incident.
