No charges will be brought over the death of a mentally ill man who died after being restrained by Met officers.
An inquest verdict of unlawful killing was overturned last year
The Crown Prosecution Service said there was insufficient evidence to justify any prosecution over the death of Roger Sylvester.
Mr Sylvester from Tottenham, north London, died in January 1999.
An inquest verdict of unlawful killing was quashed by a High Court judge last year after the officers involved claimed the ruling was "irrational".
Solicitors representing Mr Sylvester's family and those representing the police officers were informed of the decision not to take the matter further on Thursday.
Commander Alf Hitchcock of the Metropolitan Police Service (MPS) said that since Mr Sylvester's the MPS had worked vigorously to raise awareness of deaths in custody across the capital.
He said: "Although deaths in police custody in London over the past few years have been reducing, we are not complacent and have been working .... to reduce that number even further.
"I wish to take this opportunity to once again extend our deepest sympathy to the family."
Eight police officers, suspended after the original inquest verdict in October 2003, were re-instated last November when that result was overturned.
Mr Sylvester, 30, died after being restrained by officers in a padded room at a psychiatric hospital.
