Police have issued an appeal to discover the name of a mystery man suffering from severe amnesia who was found wandering the streets alone four months ago.
Baffled cops found the man, who can only speak Punjabi, in north London on August 29 last year wearing a pink turban and with a cut to his ear.
A spokesman for Metropolitan Police said investigations across Britain and immigration centres have not revealed any further details about his identity.
Officers are now keeping the man him in a secure hospital and have released a photograph in the hope that someone may recognise him.
He said: ”He just doesn’t have a clue who he is or where he is from. We’ve tried everywhere but no one seems to know who he is.”
When he was found the man was wearing an orange turban, blue zip up jumper with blue stripes on the arms, denim jeans and black trainers.
He is described as thin, dark-skinned, in his 40s, with a grey beard.
PC Lisette French, from Barnet’s Missing Persons Unit said: ”He was found in a frail and confused condition but despite now being physically well has not regained his memory.
Officers believe he may have used the name Mahinder Singh in the past.
Anyone who can help should call Metropolitan Police in 020 8733 5017.
