The trial of a man accused of shooting and killing Met Police sergeant Matt Ratana inside Croydon police station in 2020 is set to begin.
At a hearing at Northampton Crown Court in April, Louis De Zoysa, of Banstead, Surrey, entered a not-guilty plea to the offence.
During the previous session, the 25-year-old held up a whiteboard with the words “not guilty” inscribed on it as he entered his plea over a video link to a hospital.
On September 25, 2020, a deadly chest wound caused Mr. Ratana, 54, to pass away at the Croydon Detention Center in south London.

De Zoysa wrote his name and birthdate on a whiteboard to confirm them. He had previously appeared via video connection in a wheelchair and with his right arm in a sling.
De Zoysa allegedly received a gunshot wound during the event in which Mr. Ratana allegedly was shot while he was restrained.
The jury trial for De Zoysa is scheduled to begin this week before High Court judge Mr. Justice Johnson, who is based in Northampton. The trial is anticipated to continue for about three weeks.
Imran Khan KC represents the defendant and Duncan Penny KC is the prosecutor in the case.
