A stabbing in St. James late Wednesday injured two men, Suffolk County police said.

One of the victims, in what police said was a domestic incident between brothers-in-law, is a man, 45, who was taken to Stony Brook University Hospital with non-life-threatening wounds — stabs and slashes.

Police said he had surgery and is in stable condition.

The other man, 43, had minor injuries a was treated and released, police said. He was arrested on a charge of second-degree assault.

Initially, police said they responded to a 911 call at about 8:35 p.m. about a girl on a residential street with “blood on her.”

That call led police to Mills Pond Road, and Fourth Precinct officers who responded determined the girl was not hurt, police said.
