A teenage who used his car as a "weapon" to deliberately mow down and kill a mum-of-three has been sentenced to life in prison, and must serve a minimum of 17 years.

Kian Bateman, 19, was high on nitrous oxide - laughing gas - before hitting Shelley Davies, 38, outside the 4th Glamorgan Homeguard Club in Caerau, Cardiff, at 00:30 BST on 27 September last year.

She suffered complications and died in hospital three weeks later.

Her partner David Bratcher, 40, was also seriously hurt.

Bateman was cleared of the attempted murder of Bratcher, but found guilty of causing grievous bodily harm with intent, and murdering Davies.

She was taken to the University Hospital of Wales, Cardiff, but died on 18 October.

Cardiff Crown Court heard the couple had been at a music event by reggae artist and DJ General Levy at the social club that night when there was "a disagreement" involving Bateman's brother and Bratcher.

During that confrontation, Davies ended up on the ground. It was then that Bateman "made a spur of the moment decision" to accelerate his car and drive towards Bratcher, not seeing her on the floor.

The defendant drove "straight over" Davies at about 10mph, the court heard.

Bateman, of Heol Muston in Ely, then went on to hit Bratcher, who was then thrown over the bonnet of the car.
