A man is in hospital with 'life-changing' injuries after an early-morning incident at a prestigious country club in north London.
Police are at the scene at Trent Park Country Club in Bramley Road, Oakwood, with forensic investigations believed to be under way.
The man was taken to an east London hospital by paramedics after an incident is thought to have occurred shortly before 1am yesterday.
More than 17 hours later, at around 6.20pm, police were called to the hospital 'regarding the condition' of the patient, Scotland Yard said.
The force told Mirror Online his injuries are thought to be life-changing.
