AN investigation into the death of a well-known campaigner for equal rights has started.

Hadyn Burton was found hanging in his cell at HMP Winchester and rushed across the road to Royal Hampshire County Hospital where he later died.

Today the inquest into his death was opened by senior coroner for central Hampshire, Grahame Short, and adjourned to a date not yet fixed.

The 42-year-old was a member of New Fathers 4 Justice and was campaigning to highlight children’s rights including secret family courts.

He had become a well-known figure in Winchester city centre in recent months protesting at the corner of Upper Brook Street and St George’s Street in a Superman costume and with a loud hailer.

Mr Burton, formerly of Wolfe Close, Stanmore, was being held on remand at the prison facing an allegation of assault.

He was also due to be sentenced at crown court for possession of an offensive weapon, criminal damage to a police cell, and breach of a criminal behaviour order by being anti-social.
