Detectives released images of diamond-encrusted designer watches and rings during a Twitter reconstruction of a violent armed robbery yesterday.

The gunman in a balaclava - who reportedly had a sawn-off shotgun - took the extremely valuable jewellery from two young entrepreneurs and their mother at 5.45pm last Wednesday in Kingswood.

A week on from the burglary, police Tweeted images of two Rolex watches, two Chopard watches, six diamond rings and a bracelet during a real-time ‘Tweconstruction’.

After the 'reconstruction', which gave out very little information about what actually happened, police released further images to the press of a platinum cross necklace with eleven diamonds, a Cartier ladies’ watch, a Breitling watch and a Chanel watch.
