Detectives have stopped investigating an alleged rape at Glamorgan University in Pontypridd.
South Wales Police has confirmed a complaint that a 20-year-old woman was raped has been withdrawn and are no longer looking for a suspect.
The rape was supposed to have happened on September 26 in the early hours – the same night as another rape.
It was reported to police on Monday October 5 following publicity surrounding the first case when an 18-year-old student was attacked.
Police are treating the first rape report as genuine.
The 18-year-old girl was attacked at the Glamorgan Court Halls of Residence in Treforest in the early hours of Saturday, September 26.
Police were called at 4.50am on Saturday after receiving a report that a non-residential student at the university had been sexually assaulted sometime between 2.30am and 4.50am in a friend’s room at the halls of residence.
The suspect is described as around 6ft tall, of solid appearance, and was wearing gloves and a dark-coloured hooded top.
Since the attack campus security has been increased and a helpline has been set up by university bosses.
The 01443 654 660 helpline is for parents and students requiring advice or information.
Anyone with information about this incident is asked to contact police on 01443 743 678 or Crimestoppers on 0800 555 111.
