An anti-extremism campaigner said he could be scarred for life after being racially attacked outside a theatre in central London.
Maajid Nawaz said he was racially abused and hit in the face by a white male as he stood alone outside Soho Theatre.
The LBC radio presenter posted images to social media of showing a deep cut to his forehead, which he said could have been caused by a signet ring.
Mr Nawaz wrote on Twitter after the incident: “Tonight I was racially attacked while alone outside Soho theatre, from behind, as I bent down to pick up my phone.”
He said the attacker had called him “f***ing P***” before hitting him and then “ran away like a coward”.
“He took nothing,” the presenter added. “He was just a racist.”
London’s Metropolitan police said they were called to a report of racially aggravated assault at 7.10pm GMT on Monday.
An investigation has been launched but no arrests have been made, police said.
Mr Nawaz wrote on Twitter: “My forehead will probably be scarred for life. But we will find you, you racist coward, and you will face British justice.”
The presenter, a Briton of Pakistani heritage, is the founder of counter extremism organisation the Quilliam Foundation. Formerly an extremist, he later became a critic of radical Islamic movements.
He thanked those who looked after him in the aftermath of the attack as well as well-wishers for their support.
"People from all ethnicities and all faiths and none helped me yesterday," he wrote on Facebook on Tuesday morning. "It’s in that spirit that I wish to carry on my work. I do not wish to harbour hate for my attacker. I’ve already been down that path at a younger age, and I have seen how it leads to nothing good."
Mr Nawaz has asked not to be contacted while he recovers.
