DETECTIVES investigating an allegation of serious sexual assault on a 13-year-old girl believe two women, who were in Newport city centre before the incident, may have information which could help the investigation.

Police are re-appealing for information to trace two women who were in the vicinity of Newport Bus Station on Saturday March 1, between 7pm and 7.15pm, who may well have been approached by the alleged offender.

One woman, who was wearing dark clothing and carrying bags, is seen walking into the Bus Station from the direction of the Old Green Roundabout/High Street, and appears to wait at one of the bus stops.

Just after 7.10pm another woman, wearing a white top and headphones or earmuffs, appears to get off a bus and walks down Upper Dock Street towards Skinner Street and turns into Commercial Street.

Police also want to hear from anyone else who was in the Newport bus station area at about 7.15pm or was on the 19e (town centre to Malpas) bus that left the bus station at approximately 7.20pm to contact them.

A 26-year-old man from Newport has been charged with rape of a female child under 16 and is currently awaiting trial.

Anyone with information is asked to call 101 quoting log number 491 1/3/14
