The Phoenix Police Department Monday released harrowing video of a Jan. 9 officer-involved shooting in which a man holding a baby while brandishing and firing a pistol in a city street was killed.

The incident started at approximately 3:15 p.m., when 911 callers reported a man fighting with a woman at a hotel in the area. The callers also reported that a man was shooting at people and holding a baby hostage.

The second 911 call was from a woman who reported her husband had taken her baby and was shooting a gun.

As the suspect walked out of the hotel and into traffic, 911 callers reported they saw the man hold a driver at gun point.

Officers arrived within a minute of the 911 calls and saw the suspect armed and shooting a gun while holding the baby, police said.

Officers can be heard on the video telling the suspect to drop the gun.

Two other officers arrived to help.

"An officer armed with his city-issued rifle shot at the suspect when he saw the suspect point the gun at the baby and others," Phoenix PD said in a statement.

The video shows that after the suspect was down, officers immediately ran to the baby to move him to safety. The baby was not injured during the incident.

Suspect Paul Bolden, 37, was transported to the hospital where he was pronounced deceased.

Police say the woman who Bolden was reportedly fighting with was his girlfriend and the baby was his son.

The incident is the subject of both an internal and a criminal investigation, which will be reviewed by the Maricopa County Attorney's Office. "Conclusions about whether the actions of the officers are consistent with department policy and the law will not be made until all facts are known and the investigation is complete," the department said.
