SOUTH PORTLAND — A Connecticut sailor, who police allege sent two long time acquaintances to the hospital with injuries that he inflicted, is being held tonight at the Cumberland County Jail on $100,000 cash bail.

Steven Davis, 19, of Groton, Conn., who is stationed at the U.S. Navy submarine base in Groton, Conn., has been charged with elevated aggravated assault, a Class A crime, as well as aggravated assault.

Sgt. Steve Webster of the South Portland Police Department said that sometime early Sunday morning Davis, who Webster identified as a sailor, allegedly used brass knuckles to assault another man at an apartment on Sawyer Road in Scarborough. That man, who has known Davis for years, was treated for facial lacerations, and released from Maine Medical Center.

At approximately 5:15 a.m., the police department was contacted by Maine Medical Center about a stabbing victim.

An investigation by police determined that Davis had stabbed another man during the night – another long time acquaintance – during an altercation in the parking lot of the Irving Station on Main Street in South Portland.

Webster said 19-year-old Eric Thurlow of Scarborough was taken to Maine Medical Center with stab wounds. He was released Sunday afternoon.

Davis was arrested on Johnson Road in Windham by members of the Windham Police Department. He is scheduled to be arraigned in Portland District Court at 1 p.m. Monday.

“We’re not sure why this happened, but we do know that both victims had known Davis for several years,” Webster said.
