One woman has died and multiple people were hospitalised after two shootings in downtown Austin, Texas.
Emergency services were called to Sixth Street at 2:17 a.m on Sunday. Police on Twitter urged locals to stay away from the area.
Seven minutes later, emergency services responded to another call on nearby Trinity Street where the victim was being assaulted by an individual with a firearm near a parking garage.
Police later confirmed that the two incidents were isolated and not related.
The incident on Sixth Street was believed to have begun after a disagreement between two individuals led one of them to fire shots into the crowd. Paramedics at the scene said bodies with gunshot wounds were spread across the area.
A woman in her 30s was pronounced dead at the scene and four other people were injured, according to the Austin-County Emergency Medical Services.
Eyewitness Dorian Santiago told Sky News: "We heard fired shots, and people started running crazy ... I was trying to figure out what happened."
"One victim ... they were trying to do CPR to help her, but it looked like she was already dead."
Austin police chief, Bryan Manley, stressed that the incidents were not related, saying: "What we had was two separate incidents that occurred in very close proximity to each other both in location and time that made us initially believe it was an active shooter."
The second incident on Trinity Street happened after a man opened fire before being "taken down" by bystanders. The gunman was injured while being tackled and later taken to the hospital. No one else was injured.
People uploaded videos onto social media as the situation unfolded on Sixth Street. Sam Vedamanikam posted a video on his Twitter account showing the panic shortly after the shots were fired.
"I think it was a fight. Police ran immediately into it. Props to the police. We ran to 7th Street to get away from 6th," he wrote.
