(BBC) A hate crime expert set to lead a review into the cause of recent violent disorder in East Leicester has stepped down.
Dr Chris Allen said he felt he would not be able to carry out the review in a way that would meet the necessary levels of academic scrutiny.
City Mayor Sir Peter Soulsby, who commissioned the review, said levels of online abuse relating to it were disturbing.
He said he understood the decision.
The review was announced after large-scale disorder broke out on 17 September following tensions involving mainly young men from Muslim and Hindu communities.
