I think this leaves out a bit.

At around 10.07pm, Kaba made a left turn from New Park Road onto Kirkstall Gardens.[5] A marked armed response vehicle was waiting on this road.[5] Police vehicles boxed the car in, and witnesses claimed that Kaba ignored repeated orders to get out of the vehicle, and was trying to ram the Audi through the roadblock.[6] Armed officers exited their vehicles then approached the Audi on foot.[5] According to the IOPC, a police officer fired a single round at Kaba through the car’s windscreen, striking him.[5][6] He was taken to a nearby hospital, where he died of his injuries just after 12:00 am the following day.[7]
