Authorities are investigating a fatal shooting at a park in downtown Louisville in the US state of Kentucky, where demonstrators had gathered to protest the death of Breonna Taylor.
Reports of shots fired at Jefferson Square Park came in around 9pm on Saturday, Louisville Metro police said in a statement, followed by calls that the Jefferson County Sheriff's Department was performing life-saving measures on a man who died at the scene.
Shortly after, police were told of a shooting victim across the street at the Hall of Justice. That person was hospitalised with non-life-threatening injuries.
Video posted on social media appeared to show a man opening fire into the park as people scrambled for cover. The footage later showed at least one person bleeding profusely on the ground.
Officers cleared the park and police "are trying to gather as much information as possible in order to identify all who were involved in the incident," the statement said.
No information about arrests, possible suspects and the victims' identities and ages was immediately released. Officials did not immediately release additional information.
The park has for weeks been the epicentre for protests in the city after the police killings of Taylor and George Floyd.
The Saturday night shooting was at least the second during nearly a month of protests in Louisville over Taylor's death. Seven people were wounded May 28 when gunfire erupted near City Hall, prompting a statement from Taylor's mother asking people to demand justice "without hurting each other."
"Praying for our city," tweeted Kentucky state Rep. Charles Booker of Louisville late on Saturday. The Democrat is running for his party's nomination to challenge Republican Senate leader Mitch McConnell in the fall.
Taylor, a 26-year-old black woman, was killed in her Louisville home in March by police who were serving a no-knock warrant. Protesters have been calling for the officers involved in her death to be charged. One of the officers was recently fired.
Kenneth Walker, Taylor's boyfriend, was originally charged with attempted murder after he fired a shot at one of the officers who came into the home. Walker has said he thought he was defending from an intruder.
The no-knock search warrant that allows police to enter without first announcing their presence was recently banned by Louisville's Metro Council.
