The assault is reported to have occurred in the Lisfannon Park area of the city at around 11.50pm on 15th August.

Detective Inspector Harrison from Public Protection Branch said: “We’re keen to speak with three men who stopped with the victim to check on her welfare immediately after the assault occurred.
