Police are trying to identify a man who suffered a heart attack outside a London hospital on Boxing Day.
They have issued pictures of the man who has been placed in an induced coma since being taken ill near University College Hospital in Fitzrovia, north London.
A Met Police spokesman said: "Detectives from Camden are appealing for help from the public to identify a man who collapsed outside University College Hospital at around 4.30pm on Tuesday 26 December.
"He had suffered a heart attack and is currently in an induced coma. Medical professionals have described his condition as life threatening. When found he was not carrying any identification.
"Due to his poor state of health police are keen to trace his family as soon as possible.
"Officers have released a photograph of the man in the hope that a family member or friend may recognise him and come forward.
"He is of light skinned black or Asian origin and it is possible that he may be homeless."
He said anyone able to help should call CID at Central North Command Unit by dialling 101.
