The Independent Police Complaints Commission says it will be looking into whether police officers should face criminal investigation after the death of 39-year-old Leon Briggs in custody.
At this stage we believe there is an indication that potential criminal offences may have been committed including gross negligence and/or unlawful act manslaughter, misconduct in public office, and/or offences under the Health and Safety at Work Act 1974".
"We will also be considering whether any potential disciplinary offences have been committed."
