A manhunt was underway in Austin after a gunman opened fire on a crowded downtown street as bars were closing Sunday, killing one person and wounding four others, police said.

Austin Police Chief of Staff Brian Manley said five people were shot shortly after 2 a.m. on Sixth Street, a bustling 7-block entertainment district lined with historic buildings that now house bars, upscale restaurants, trendy shops and music venues.

A woman in her 20s was pronounced dead at the scene, and three other women were taken to University Medical Center Brackenridge with gunshot wounds that were not considered life-threatening. One other person refused treatment, he said.

"It was a very chaotic scene," Manley said. "A lot of people running in different directions."

Manley said police, based on descriptions provided by witnesses at the scene, were looking for a light-skinned black male in his 20s.

“We had one individual who was initially noted as a person of interest," Manley said. "That person’s status at this point is undetermined."

Sam Vedamanikam, 26, told Austin's Statesman newspaper he and several friends were walking to their car when four or five shots rang out.

“There were just tons of people on Sixth Street and I see all of them jump toward the ground,” he said. “A lot of people were screaming.”

Manley said it was not clear if the shooter and victims knew each other. Police were attempting to collect video from the scene, he said.

"We know a lot of individuals have captured the incident or the aftermath of this incident on their cellphones and other devices,” Manley added. "We ask that anyone who has video ... please forward that to us.”

Seven minutes after the first incident, police received reports of another incident several blocks away in which a suspect fired a gun at another person in a parking garage, Manley said. No one was injured, and nearby individuals disarmed the suspect, who was injured and transported to a hospital.

The two incidents together led police to tweet out an active shooter warning, Manley said, but police now believe the shootings were not related.

Police secured both crime scenes and warned people to avoid downtown.

"On behalf of the Austin Police Department we wish to extend our deepest condolences to the family and friends of the young woman who lost her life to this senseless act of violence and wishes for a speedy recovery to the individuals wounded," Police Chief Art Acevedo said in a statement. "The men and women of the Austin Police Department will work tireless to identify and apprehend the person responsible."
