Detectives are appealing for information after a young girl was sexually assaulted by a man whilst walking through Waterloo Underground Station.
At around 10pm on Friday 14 October a woman had alighted from a Jubilee line train when a man approached her during her walk towards the station exit. As the man walked past her, he extended his hand and touched her inappropriately.
Immediately after doing so, the man then approached an 11-year-old girl and her family where he also extended his hand and touched the girl inappropriately.
The young girl's family then approached police officers on the station concourse and reported the assault. However, police have been unable to identify the first victim.
Officers from the British Transport Police have launched two appeals: one to trace the man responsible and another to find the first victim and encourage her to contact police as soon as possible.
"This was an upsetting assault for this young girl and we are determined to trace the person responsible," said Detective Constable Suleman Yazdani.
"I am keen to speak with this man in the CCTV images; I believe he has very essential information that will assist my enquiries. I am also very interested to speak with another woman who was walking behind this family as I feel she was also a victim of a similar assault.
"We simply will not tolerate unwanted sexual behaviour on the underground. If you are ever a victim of sexual assault, please report it to us so we can trace and stop these perpetrators."
