At 7am this morning, a Citybus was traveling along Sau Mau Ping Road in Kwun Tong when, all of a sudden, a man crossed the road in front of Po Tat Estate.
The driver was unable to brake in time to prevent a collision and the man was thrown three metres, reports Apple Daily.
The victim was seriously injured and is now in critical condition at hospital.
A lorry behind the Citybus rear-ended the double-decker when it braked.
The lorry driver was sent to hospital with minor injuries.
