Police are asking for help to trace this woman. Thought it might be worth asking:
'Police in Glasgow are trying to find a woman who helped the victim of a sex attack in the city centre.
They say she is a key witness to the serious sexual assault of a 21-year-old woman on 9 June.
The incident happened around Sauchiehall Street and Sauchiehall Lane just after midnight.
After an extensive review of CCTV footage, police are keen to speak to a woman who spoke to the victim outside the Boots store on Sauchiehall Street.
The store is located at the Charing Cross end of the street, near to Glasgow Dental Hospital. The women spoke for around 15 minutes at about 00:30.'
