Police have released a picture of a man wanted over an acid attack in Manchester.
Officers have tried and failed to trace Jonathan Joseph, 31, for seven months.
Two men had acid thrown in their faces after a row over a cab in the city centre, at New Year.
Detective Constable Adam Cronshaw says: "This was an attack which has had a profound impact on both of the victims. We have made a number of enquiries to trace Joseph as part of our investigation into this attack and urge anyone who knows where he is to call us."
