An investigation into the police operation during which reggae singer Smiley Culture died has found no evidence of a criminal offence.

The Independent Police Complaints Commission (IPCC) investigated the actions of the individual officers, as well as the planning of the operation as a whole.

The singer died from a single stab wound during a police raid at his home in Surrey on March 15. His family had demanded more information after a report that he stabbed himself during the raid.

An inquest into his death three days later revealed he stabbed himself through the heart with a kitchen knife as four Metropolitan Police officers carried out a search of his home in Hillbury Road, Warlingham.

Smiley Culture died at the scene despite attempts at resuscitation.

The 48-year-old was accused of conspiracy to supply cocaine and had been due to face trial.
