DETECTIVES are due to formally interview a teenage girl today (Thursday) over her allegation of being sexually assaulted at Castle Green, Hereford.

A 28-year-old man arrested yesterday (Wednesday) over the allegation has since been released on police bail.

The teenager was found by an ambulance crew in Capuchin Lane, near High Town in Hereford, after a 999 call reported a young woman collapsed and unconscious there just before 1am yesterday.

She was taken to Hereford County Hospital where the sexual assault allegation was made.

The attack is alleged to have occurred in an area close to the Castle Green toilets, which was sealed off as a crime scene for much of yesterday.

A 28-year-old man subsequently arrested in the city was this morning confirmed as released on bail.

The 17-year-old, now out of hospital, will be formally interviewed over her allegation today.
