A METROPOLITAN Police officer will not face misconduct charges over the death of Rashan Charles who was restrained in an “unorthodox” way on a shop floor, a watchdog ruled today.

The young black man died last July after being chased into a store in Dalston, east London.

A post-mortem examination concluded that he died from a heart attack after a package he swallowed, found to contain a mixture of paracetamol and caffeine, blocked his airway.

The Independent Office for Police Conduct (IOPC) found that the officer, identified only as BX47, had not done his job satisfactorily but was not guilty of misconduct.

IOPC London director Jonathan Green said BX47 was “responsible for some basic failings,” which represented “a failure to perform his role satisfactorily, either through a lack of competence or capability.”

But Mr Green added that those failures were “not deliberate and it is acknowledged by witnesses present at the scene, supported by expert evidence gathered in this investigation, that BX47 did his best in difficult circumstances.”

The IOPC found that the decisions to stop Mr Charles’s car and chase him on foot were justified and that the officer's restraint technique, although “unorthodox,” did not contribute to his death.

BX47, who did not follow first-aid protocols and also failed to switch on his body-worn video camera, will now be put through internal Met performance procedures.

In June, an inquest found that Mr Charles’s death was accidental, a verdict that his great-uncle, retired chief inspector Rod Charles, branded a “farce.”
