Police have released a CCTV image of a man they want to question after two people were stabbed at Oxford Circus tube station in London within 24 hours of each other over the weekend.

Emergency services were called to two incidents in the early hours over the weekend, which police said were connected. The first incident took place at 3.40am on Saturday and the second just after 1.30am on Sunday.

A 23-year-old man injured on Saturday and a 43-year-old man were treated in hospital for stab wounds, British Transport Police (BTP) said. Police have not yet made any arrests.

DCI Gareth Davies said: “There is absolutely no place for violence on the rail network, and detectives are working at pace to investigate these two connected incidents.

“Passengers will see an increased police presence at the station while officers carry out their inquiries. We are urging anyone who was in the area at the time and may have seen these incidents take place or events leading up to, to get in touch and assist us with our inquiries. Any piece of information might be vital for our investigation.”

Witnesses have been asked to text BTP on 61016 or call 0800 405040. They can also contact Crimestoppers anonymously on 0800 555111.
