We are releasing CCTV images of a man officers would like to speak to in connection with incidents of sexual assault and harassment in London.
A 21-year-old girl reported that on two different occasions in March this year, she has noticed a man who she does not know following her from a Victoria Line train and then apparently waiting for her at the escalators at Walthamstow Central underground station.
The man has been acting suspiciously and has been making the victim feel uncomfortable.
She has not been injured during these incidents but has been left feeling upset and nervous about using the underground.
Officers have linked the incidents with a sexual assault which happened at Marble Arch station on 23 February this year.
A woman in her forties was approached by a man who helped assisted her to the platform and then began making sexual comments and touching her inappropriately.
Investigating officer, Det Con Andrew Parkinson, said: “I would like to speak to the man shown in the CCTV images as he may have information which could help with the investigation into these two incidents, which we now believe are linked.
“The harassment against the woman at Walthamstow Central has left the victim feeling very intimidated and unsafe. Officers are supporting her as the investigation continues.
“It is vital that we trace the man responsible so that we can establish the full circumstances of the harassment incidents.
“Similarly we are still appealing for information regarding the sexual assault at Marble Arch.
“If you have any information at all, no matter how insignificant it may seem to you, or if you recognise the man in these CCTV images, please contact me as soon as possible by calling 0800 40 50 40 or texting 61016 quoting reference number 175 21/04/17.”
