A watchdog is investigating how police initially responded to an incident that led to the death of a man.

Three people have been charged in connection with the death of William Brittle, 60, in Paisley last week.

But now the Police Investigations & Review Commissioner or PIRC has launched a formal inquiry in to how officers handled their initial response to the incident.

Mr Brittle, a grandfather, died in Paisley's Royal Alexandra Hospital on June 7 after the incident on June 6. A man, George Sproule, 45, has appeared in court charged with culpable homicide. Another man, Christopher Reid, 26, and 41-year-old Nicola McCann, have been charged with assault.

Mr Brittle, of Broomlands Street, Paisley, was a well-known "larger than life" figure n Paisley.

Neighbours have told the local Paisley Daily Express that he put speakers in his windows and played music in to the street.

Earlier this year in court Mr Brittle admitted making racially aggravated threats to murder Muslims.

Locals, however, said that he was a "laugh". His son, also William Brittle, said on Facebook: "The whole family are still in shock and don't know the full story yet but once again another good Person has been taking from us."

Mr Brittle also unveiled a new tattoo with "RIP dad".

A spokesman for PIRC said the investigation had been directed by the Crown Office, who are responsible for criminal investigations in to the police.

He said: "A report into the findings of the investigation will be submitted to the Crown Office in due course."
