A sex attacker may rape in the future after gaining confidence from two assaults, police have said.

Women in Bicester have been warned not to walk alone after dark following a sex attack in George Street last week, which could be linked to a November assault. A team of officers are working on the case and extra high-visibility patrols have been put in place.

Anyone with information should contact Bicester CID on 08458 505505 or Crimestoppers anonymously on 0800 555111.
