Philip O. Coleman, 38, was arrested Wednesday evening after he alleged beat his 69-year-old mother, police said in a statement, adding he "became combative" and spit blood on the faces of police officers and a police supervisor.
As he was taken from the police station to court Thursday, "he again became combative" and a stun gun was used "to gain control of the subject," a police statement said.
Instead of court Coleman was taken to Chicago's Roseland Community Hospital, where the police statement said "he became physically aggressive with hospital staff and accompanying (officers). Once again, reasonable force was employed, including a Taser deployment."
Coleman was admitted to the hospital, given a sedative and died Thursday afternoon, the Chicago Tribune reported Friday.
The Independent Police Review Authority is investigating the incident, and agency spokesman said.
