PHOENIX — Authorities say a man who was naked when he attacked a police officer last week has died.

Phoenix police say it will be up to the Maricopa County medical examiner to determine the cause of death for 40-year-old Casey Wells.

Officers received a call about indecent exposure in a neighborhood on Feb. 4.

They found Wells with no clothes on and acting erratically.

Police say Wells then got into a fight and attacked an officer, who deployed a stun gun.

Wells was taken into custody and then taken to the hospital.

Police say Wells died Sunday.
