SCOTTSDALE, Ariz. (AP) - Police say they are investigating the death of a 53-year-old man who was being held at Scottsdale City Jail.
The Scottsdale Police Department said in a Thursday statement that Matthew Chase died at the jail that morning.
The statement says Chase was arrested without incident on an outstanding warrant and booked into the jail.
It says jail staff noticed he appeared to be bleeding from the nose early Thursday but he was standing, alert and denied needing medical attention.
Jail staff contacted the city fire department anyway, but Chase lost consciousness and fell to the ground before fire personnel arrived. Chase died despite life-saving efforts and being taken to a hospital.
The Maricopa County Medical Examiner will determine the cause of death.
