CRAZED gun killer Louis de Zoysa was today handed a whole life order for the murder of Met police Sergeant Matt Ratana.
The 25-year-old was still handcuffed when he pulled out a hidden antique revolver and fired four shots.
Sergeant Matt Ratana, 54, was blasted twice during the horror at Croydon Custody Centre on September 25, 2020.
The dad later died from his wounds in hospital.
Being handed a whole life order means the killer will die behind bars – joining a depraved club of Britain’s most twisted offenders.
