Police are hunting a man after a woman was sexually assaulted on a train heading towards Bromley.
The British Transport Police (BTP) has released an image of a man officers would like to speak to in connection with the incident, which happened on Thursday, 30 October, just before 8pm.
Police are investigating reports of a man sitting opposite the victim and sexually assaulting her on board a train between London Bridge and Hayes in south-east London.
The man pictured has not been accused of the assault. Officers say they would like to speak to him because he may have information that could help the investigation.
Anyone who recognises the man is asked to contact BTP by texting 61016 or by calling 0800 40 50 40, quoting reference 998 of 30 October.
Information can also be passed anonymously to Crimestoppers on 0800 555 111.
British Transport Police issued a similar appeal last month after a man was sexually assaulted on a London Bridge to Sevenoaks service, releasing a CCTV image of a man officers wanted to speak to in that case too.
Victims of sexual offences are entitled to lifelong anonymity, and anyone affected can contact police or a support service for help.
