British media earlier had reported that the stab wound was self-inflicted.

The Independent Police Complaints Commission says an investigation is ongoing into the death of the artist – whose real name was David Emmanuel.

The watchdog said Thursday that facts established so far show that four officers arrived at Emmanuel’s home at around 7 a.m. on March 15 and an ambulance was called to the scene at around 8:30 a.m.

Emmanuel, 48-years old, shot to fame in the 1980s with hits such as “Cockney Translation” and “Police Officer.”
