Jermaine Baker, 28, from Tottenham in north London, died from a single gunshot wound after an intelligence led operation carried out by the Met’s Organised Crime Command and Specialist Firearms Operational Command Unit on December 11, last year.
Nathan Mason, Gokay Sogucakli, Ozcan Eren and Eren Hasyer were arrested following the police operation near Wood Green Crown Court.
They all appeared at Woolwich Crown Court via video link from HMP Belmarsh, wearing tracksuits apart from Eren who was dressed in jeans and a sweatshirt. The youngest of the men, 18-year-old Sogucakli clutched what appeared to be prayer beads.
Eren, 31, of Douglas Road, Wood Green, and Hasyer, 25, of Kettering Road, Enfield, are charged with conspiracy to aid the escape of the two prisoners.
Mason, 30, of Vicarage Road, Tottenham, and Sogucakli, of the Roundway, Tottenham, face the same charge, as well as possessing an imitation firearm and using a motor vehicle taken without the owner’s consent.
All four are due to next appear at Woolwich Crown Court on February 29 for a plea hearing.
Representatives of the men indicated they would be contesting the case.
Two men, Izzet Eren, 32, and Erwin Amoyaw-Gyamfi, 29, were later jailed for 14 years each at the court for firearms and driving offences.
Following the shooting, the Independent Police Complaints Commission (IPCC) launched a criminal homicide investigation into the death. This could see police face murder or manslaughter charges.
A firearms officer was suspended by the Met following a suggestion by the IPCC.
