Women and members of the LGBT community in Brighton say they have been forced to patrol areas of the city at night following an increase in sexual assaults.

Volunteers - some of whom have been attacked themselves - will offer a 'buddy-up system' to walk revellers home or to safety. The move follows a vigil in Brighton's Pavilion Gardens. Andy Dickenson reports.
