Four men on two scrambler bikes battered the window of a jewelry shop in Merseyside, North West England before giving up on the burglary attempt.
The robbers used sledgehammers to try and force their way into the shop as stunned bystanders — including terrified families and children — looked on.
But they eventually left as they came after the glass-front refused to give way.
Among them was shop manager Keith Leicester, who said: “It was a terrifying experience and we were all shaken up by it.
“The first we knew about it was when we heard a number of motorbikes, followed by the sound of loud banging as they attempted to smash the glass in.
“This activated the alarms and also triggered the anti-theft fogging device, which filled the shop with smoke. We just locked the door and waited for it to be over.”
The incident is currently under investigation.
