A man doing handyman labor was shot Friday in the Tower District, and an officer was treated after police responded, Fresno police said.

Officers responded about 6:30 a.m. to a yard on Ferger Avenue north of Olive Avenue after reports of a shooting, Sgt. Diana Trueba Vega said.

Police said they found a victim in his 40s with a single gunshot wound to the upper torso.

He was taken to Community Regional Medical Center, police said. He was in stable condition as of about 11 a.m., Trueba Vega said.

Officers were outside a home on the same street at about 9 a.m. calling to a man inside to come out. After a short standoff, the man surrendered to police and confessed to the shooting, according to police.

Trueba Vega said the man, who was in his 50s or 60s, shot the victim as the victim did yard work next door. It was not clear if the men knew each other. A motive for the violence also wasn’t immediately clear, she said.

The man was arrested.

Police then entered the home and found two more men inside, one of whom was unconscious from what was believed to be alcohol. Trueba Vega said paramedics treated him as a precaution.

An officer who entered the home began to feel sick, possibly from being exposed to an illegal substance, and was also treated by paramedics as a precaution, she said.

Trueba Vega said police intended to file a search warrant for the house to find a potential substance.
