A thug armed with a baseball bat has tried to attack a family inside their car - before he is chased off by a young girl.
A baby aged seven months and a three-year-old were in the back of the vehicle when the man launched the vicious assault, at one point yanking open a car door and leaning inside.
Amazingly, the attack ends when a 12-year-old girl emerges from the house and charges straight at the man.
The disturbing CCTV footage was filmed in Hatfield, Hertfordshire, on Saturday, November 11.
The reason for the vicious ambush on the family is not clear and police do not appear to have been informed.
