CCTV released in hunt for Preston rape suspect
A man suspected of raping a woman who became separated from her friends is wanted by police.
The 18-year-old victim was attacked on a grassy area in Preston city centre at about 04:20 BST on 22 September.
Police believe the attacker boarded an 08:00 train to Bolton, before heading to the town's bus station and catching a 37 service to Manchester.
The suspect, captured in CCTV images, is thought to have approached other women on the same night.
Police said they were "determined to find him", and are trying to establish which bus stop he got off at.
He was wearing trainers and jeans with a rip on the knee.
