A man has been subjected to a sexual assault on his morning commute to work on the Victoria Line.
The incident happened at around 7.30am on Wednesday March 22 on a southbound Victoria Line train.
The 38-year-old victim boarded the train at Finsbury Park, and stood, as it was busy.
During the journey, a man positioned himself very close to the victim, pressing himself against him and touching him inappropriately, in what police are calling a "prolonged" assault which continued until the victim got off the train at Kings Cross.
Investigating officer, detective constable Suleman Yazdani from British Transport Police, said: “This was a disgraceful and prolonged assault committed on a busy commuter tube service.
"As you can imagine this was a frightening experience for him as he quite rightly did not expect or want this man to touch him.
BTP describe the suspect as a man of slender build and of around 5ft 7in tall.
He is believed to be in his mid-twenties and has blue eyes and blond hair which was curly on the top.
At the time of the incident, he was wearing black jeans, trainers, a camouflage jacket and was holding a bright rucksack.
He also had a black earning in his left ear.
Detective constable Suleman Yazdani, added: "If you know someone who matches the description then please get in touch as your information could be vitally important.
“Unwanted sexual behaviour such as this will never be tolerated and we work closely with our partners throughout the capital to encourage victims to report offences.
"Recently, we launched a refreshed version of the highly successful Report it to Stop it campaign, to tackle under-reporting and raise awareness of the reporting services.”
