American R&B artist Omarion withdrew from a scheduled appearance at London's DSTRKT club last night, just days after the venue was accused of operating a racist door policy.

He made the announcement on Twitter, just hours before he was due to perform at the popular West End nightclub.

Hundreds of fans took to the social media site to praise his decision. One said: "Thank you for not turning a blind eye to their racism!"

The club has come under increasing pressure in recent days, following accusations it refused entry to some women because their skin colour was "too dark".

It prompted a social media campaign against the venue and protests outside the club during the week.
