A boy aged just 12 may be responsible for a string of sex attacks around a university campus.
Greater Manchester Police are linking the assaults which have taken place in the last month near the University of Manchester and have released an e-fit image of the young offender which they said made the incidents "even more shocking".
The first two attacks took place within 15 minutes of each other on Saturday September 21.
A 27-year-old was approached from behind and grabbed in Lloyd Street North at 6.15pm before she screamed and the offender ran off.
The next incident followed in Oxford Road when a 21-year-old woman was approached by a boy who made lewd comments as she left John Rylands library.
She carried on walking on Moss Lane East and was sexually assaulted by her assailant who was described as a young Asian boy aged 12 who wore green jeans and glasses.
The third attack took place at the Manchester Science Park in Lloyd Street South at about 2.15pm on Saturday October 5.
A 32-year-old woman was approached by two young boys and sexually assaulted by one of them described as being Asian, 12 to 13 years old, of slim build, with a small frame who wore baggy trousers and carried a rucksack on his back.
She pushed the boy away but he approached her again and sexually assaulted her for a second time before running off towards Pencroft Way in company with the second child, also described as a young Asian boy.
