DENVER (AP) -- A man involved in an altercation with two police officers and two security guards at the Denver Zoo has died.
Police spokesman Sonny Jackson says officers were called to a disturbance at the zoo around 5 Monday evening. He says the man scuffled with the officers and guards, who were injured.
In a statement, Denver police say their officers tried to use a Taser on the out-of-control suspect, but that it failed. After several minutes of fighting, officers finally were able to place the suspect in custody.
Jackson says while awaiting the arrival of paramedics, the man then convulsed and stopped breathing, and the officers administered CPR. The man died at the hospital about an hour later.
The man's name and age haven't been released. Drugs and drug paraphernalia were found on the man, according to police. An autopsy will be performed.
Jackson says it's unclear what started the disturbance. A woman with the man wasn't injured, so police don't know if it was a case of domestic violence as initially believed.
The officers and guards had bite wounds, sprains and other injuries. One was treated at the hospital and released.
