ROCHESTER – A 49-year-old man was airlifted to a Maine hospital after receiving a serious head injury during an assault at a local long-term hotel along Route 125 Thursday evening.

Police, firefighters and emergency personnel responded around 8 p.m. after the man was struck during an incident at the Residence Inn at 182 Milton Rd., according to Deputy Police Chief Scott Dumas.  The identity of the man has not been released.

Dumas said police are looking into whether the serious head injury was caused by an object or another person.

“We anticipate making an arrest this afternoon,” Dumas said, adding more information will be released at that time.

By the time firefighters arrived at the scene Thursday evening, paramedics from Frisbie Memorial Hospital were already treating the man, according to Assistant Fire Chief Mark Dupuis.  He said firefighters helped paramedics by providing a driver and transporting the patient to Skyhaven Airport on Route 125.

Dumas said a flight from the Dartmouth-Hitchcock Advanced Response Team (DHART) transported the man from Skyhaven to Maine Medical Center in Portland.
