Police are appealing to find a vulnerable 35-year-old man who was last seen at his home in North London two days ago.
Bashir Marhoon, from Russell Square in Camden, was last seen by his carers on Saturday at 6pm.
The Metropolitan Police said officers are becoming increasingly worried about his safety due to the challenges Bashir has with his day-to-day needs.
Bashir is described as being 5ft 8in, of medium build, with black hair and glasses.
He was last seen wearing a navy baseball style shirt, with a red image on the front, dark navy jogging bottoms and black trainers.
Bashir also walks with a limp and is known to sometimes engage with strangers, though lacks the capacity to fully understand what he may be doing, Scotland Yard said.
Officers believe he may be travelling across London using public transport.
He has an Oyster card and is fascinated with public transport.
Detective Chief Inspector Sarb Kaur said: “We are very worried about Bashir’s safety and would urge anyone who may have seen him to contact police.
“Please approach Bashir with care as he may be confused and suffers with learning difficulties.
“Bashir’s family are understandably incredibly concerned.
“Local officers have been carrying out a number of enquiries in an effort to trace him and we are now turning to the public for help.
“Please get in touch if you have seen Bashir.
“As time passes we are growing increasingly anxious about his welfare.”
Bashir’s mum Faridah, said: “We are very worried as he is very vulnerable and often rides the trains and buses to the end of the journey.
“We urgently need the public’s help to find him.
“Please take a look at these images we are making public today and get in touch with the police if you have any information.”
Anyone who sees Bashir has been asked to call 999 providing the reference 5841/24MAY.
