Alarming footage shows a robber lunging at Tesco staff with a knife after one supermarket worker bravely wrestled stolen goods from him.
Josh James, 33, waved a blade at staff before he violently smashed the door down at the supermarket in Bristol.
Footage played in a court shows James come within inches of slashing the unarmed shop worker and then damaging the glass, amid a five-month spree of burglaries and robberies.
