A number of alleged sexual assaults have taken place between February last year and now.

The male suspect is reported to have touched female passengers on more than 10 occasions.

Detective Sergeant Matthew Brown, of the Met’s Roads and Transport Policing Command, said: “We are aware of social media posts regarding this individual and appreciate the concern that these incidents will cause. We would like to assure the community that we are doing all that we can to identify and locate the suspect.

“While his face is covered in the images, we are hoping that anyone who knows him will recognise him or his clothing and get in touch.

“Similarly, if you believe that you may have been targeted by this man, but have not yet spoken with police, please do get in touch – at the very least so that we can know that you are okay and are being supported.”

Anyone with information can contact police on 101 or post via X @MetCC quoting reference CAD 8412/21Sep.
