Police have appealed for information after a woman was assaulted in Westminster.
On Sunday 28 October a man approached a woman entering a flat on Craven Terrace at 8.45pm and slashed her across the bottom with a sharp object before fleeing the scene.
The victim suffered a superficial wound which required hospital treatment.
CCTV footage shows the man police wish to speak to. It is thought to be a random attack and anyone who can identify the man in the video is urged to come forward.
He is believed to be of medium to tall build and was wearing a big jacket and a hat at the time of the assault.
Detective Constable Yousuf Bhamjee, from Westminster CID, said: "This assault has had a significant impact on the victim. I am appealing for anyone with information to get in touch with us on 020 7321 7620."
