The 48-year-old who plays Ian Beale in the BBC One soap, opened up about the horror incident as he revealed his recovery has been “incredible”.
Adam took to Twitter to explain why he hadn’t posted on his food blog since July last year and went on to say it was because of a busy work schedule and his 16-year-old son being involved in a car accident.
The soapstar said: “Our son Sam was crossing a road in London and got knocked down. The London Air Ambulance service attended him and placed him in an induced coma which he was in for 42 hours. He also had a 5 hour operation to rebuild his pelvis.”
The longest-serving actor in EastEnders revealed the pair were planning on running the marathon for the London Air Ambulance service before his son’s accident.

He continued: “Sixteen weeks on, his recovery has been incredible. We are both training to run the Virgin Money London Marathon in April for the Air Ambulance Service, something we were planning to do before he had the accident.
