Coroner's training call over Hywel Hughes' custody death

4 July 2014 Last updated at 21:05 BST

A coroner who investigated the death of a man in police custody after he was ejected from a nightclub has warned others could die unless police training improves.

An inquest last month found the actions of two officers contributed to the death of Hywel Hughes, 32.

He died of traumatic asphyxia at hospital in Bangor in May 2003 after he had been restrained by security staff.

Karon Monaghan QC has called for improvements in the training given to officers on "positional asphyxia".

Roger Pinney reports.
