Police are hunting for a man and a woman after an 'unprovoked' attack on a Polish woman at a London Underground station.

The 26-year-old victim was leaving Goldhawk Road station, west London, at about 6pm on October 12 when she was approached by a man and a woman.

They began questioning her nationality before launching an attack, say police, with the pair kicking and punching her several times.

She was left with bruising and swelling to the right side of her face.

Police have released CCTV images of a man and a woman who they wish to speak to in connection with the incident.

Detective Constable Oliver Carne said: “I am very keen to speak to the people in the CCTV images I have issued today, as they may hold vital information that could help us in our investigation.

“I would like to hear from anyone who was at Goldhawk Road station in the early evening of 12 October, or in the area and witnessed the attack.

"If you know the two people in the CCTV images, please get in contact with BTP.”
