THE grieving mother of Chris Kaba has demanded answers from the police watchdog six months on from the fatal police shooting of her unarmed son. 

The 24-year-old was shot in the head by a firearms officer after his car was pursued by officers in Streatham Hill, south London, on September 5. 

The Metropolitan Police officer, known only as NX121, has been suspended and interviewed under caution after the Independent Office for Police Conduct (IOPC) launched a homicide investigation.
