POLICE are hunting a sex attacker who subjected a woman to a "terrifying" assault on a cycle path near Ebbw Vale at 1am on Saturday, leaving her traumatised.

The 22-year-old victim was walking along the unlit track, known as Black Path, from Brynmawr to the Beaufort area of Ebbw Vale when a man attacked her.

A section of the path behind Beaufort Hill Junior School and Penycwm Special School was sealed off by police at around 8am on Saturday.

Detectives are urgently trying to trace a male suspect described as white, between 20 and 40 years old, approximately five foot eight, wearing dark clothing and with short dark hair.

Officers combed the track and grass verges on either side yesterday afternoon, and carried out house to house inquiries in surrounding streets.

Anyone with information or who was in the area at the time should call Gwent Police on 01633 838111 or Crimestoppers anonymously on 0800 555 111.
