A jury has failed to reach a verdict in the case of a suspected sex attacker who was tracked down on Facebook.
Alpha Gray, 30, of Holloway, north London, denied attempted rape and sexual assault. The jury was discharged after 11 hours of deliberations.
He was arrested after a woman who was attacked in May in Tufnell Park, north London, said she had traced him through the social networking site.
Mr Gray will face a retrial at the Old Bailey early in the new year.
He denied the charges, saying he had left the area in a cab before the attack.
