Police say they're continuing to investigate a sexual assault in Weston almost a month ago.

A woman was attacked by a man in his 20s as she walked along the cycle track between Searle Crescent and Hutton Moor Road at 6am on June the 17th.

Detectives have now released an eFit image of the offender - adding to the dark red hoody with 'F-S' in yellow lettering on it, which they found near the scene.
