Police have dropped charges against the ex-diversity officer for Goldsmiths' students' union, who was due to appear in court for allegedly tweeting “#killallwhitemen”.

Bahar Mustafa, the former welfare and diversity officer at the New Cross based students’ union, was charged with sending a threatening message and sending a grossly offensive message via social media.

The 28-year-old, from Edmonton in Enfield, was due to appear at Bromley Magistrates’ Court on Thursday (November 5).

Met Police told the Guardian today the case had been dropped.

But the Crown Prosecution Service said one of the complainants has now requested a review of the decision to discontinue the case.

Officers at the Lewisham community safety unit launched an investigation in May after receiving a complaint of racially motivated malicious communication.

During her time as the elected welfare and diversity officer Mustafa became the centre of a media storm, after allegedly tweeting the hashtag “#killallwhitemen” and banning white men from an event on diversifying the university's curriculum.

A video then appeared online of Ms Mustafa stating it was impossible for her to be racist because she is an ethnic minority woman.

Freedom of speech groups criticised the charges using a social media campaign titled #IStandWithBaharMustafa.

A CPS spokesperson said: "Following the decision to discontinue this case one of the complainants has now requested a review of this decision under the Victim's Right to Review Scheme.

"It would not be appropriate to comment further on this case until this process has been completed."
