Police in north London are asking mental health nurses to be on the lookout in case they treat an escaped prisoner.
Enfield police are renewing their appeals for information on the whereabouts of Fida Utmanzai, an Afghan national who escaped from a medical facility in Edmonton in March 2010. He was serving an indefinite life sentence for manslaughter.
Fida Mohammed Utmanzai, aged 21, was born in Afghanistan. He is around 6 feet tall, thin and with short black hair. He is also known to have cigarette burns on his arms.
The last known sighting of Mr Utmanzai was in Wandsworth High Street on the night he went missing. Despite extensive enquiries he has yet to be traced.
He has previous connections to the Tottenham, Fulham and Putney areas of London. He has also spent time in Newcastle.
He was detained under the Mental Health Act indefinitely after being convicted of manslaughter in 8 January 2010.
Health professionals with any information are asked to please contact Detective Sergeant Miles Manning from the Metropolitan Police on 0208 345 1223 or Crimestoppers on 0800 555 111.
