This is the dramatic moment that a gang of four thieves made off with almost half-a-million pounds worth of jewellery and watches after loading a 750kg safe into a Ford Focus.
The raid on a 'secure' business park in Egham, Surrey, took place just after midnight last Monday, devastating the young owners of the jewellery firm who were not insured for loss of stock.
Unable to enter the gated complex that is home to firms including Samsung, the raiders took their car off road, cut through the fence of an adjoining park and then through a second fence leading into the Meadlake Place Business Centre's car park.
CCTV footage shows three of the men, wearing balaclavas and overalls and armed with sledgehammers and crowbars, smash through two sets of glass doors leading into the lobby of 1 Meadlake Place.

The men then ran up the fire escape stairs to the first floor where they crashed through a 300kg wooden security door before bludgeoning their way into the offices of jewellery firm 247 Kettles.
The firm's co-founder Conor Thornton said: 'We had bought a safe weighing 750kg for our stock and as we were on a locked business park with 24 hour security, we thought that would make us impenetrable.
'In the event, they used a sledgehammer to smash our floor to ceiling windows and then shoved the safe out onto the road below.'
The CCTV footage shows some smaller boxes landing on the road outside before the mighty safe, containing watches and jewellery worth £400,000, hit the deck with a puff of dust.
The men used a sledgehammer to smash through two sets of glass doors and make off with £10k in cash and a 750kg safe containing luxury Rolex watches and jewellery worth £500k
