Louisville, Kentucky shooting: Gunman bought weapon last week

The gunman who killed five people at a bank in Louisville, Kentucky, on Monday legally bought the weapon he used the week before, police have said.

He purchased the AR-15-style semi-automatic rifle on 4 April.

At a news conference, officials said two people - including a police officer - remain in intensive care.

Louisville Mayor Craig Greenberg called for a change in Kentucky law to prevent the weapon used in the attack being bought at a police auction in future.

Police confirmed that bodycam footage captured by first responders will be released later.

A police officer who graduated into the force last month was struck in the head on Monday and remains in critical condition at Louisville hospital, officials said.

Four people have been released from hospital overnight, one other person remains stable in intensive care, while two others continue to be treated for non-life threatening injuries.
