Police officer
PC Simon Read faces a misconduct hearing over the alleged incident at Tesco in Cambridge.
The family had not been able to see their elderly relative for nine months.
The Dorset officer was cleared of murdering Parry, his lover, but admitted manslaughter.
The officer was attempting to detain two men who were trying to rob a grocery store in Westminster, police have said.
He called her a "fat bitch who couldn’t even get having a baby right". But when Tracy reacted, a nightmare she "never thought she'd get out of" began.
An investigation into how the suspect was able to kill Sgt Matt Ratana inside a custody is being carried out by the police watchdog.
The 54-year-old was shot at the south London station in the early hours of Friday morning.
The suspect is believed to have turned the gun on himself and is in critical condition in hospital.
It follows the announcement that none of the officers involved in Taylor's death would be charged with murder.
The charges were tied to shots fired into neighbouring apartments, but not Taylor’s. None of the three police officers involved in the shooting were charged with murder.
