A man has been charged with the murder of his disabled father.
John David Keen, 48, who used a wheelchair due to a heart condition, was found stabbed in a basement flat in Eastcote, north-west London, on 21 December.
A post-mortem examination found that the father-of-four's death had been caused by multiple stab wounds.
His son Jonathan Keen, 21, of Woodlands Avenue, Eastcote, was later charged with murder and will appear at Uxbridge Magistrates' Court on Friday.
