A video showing burglars raiding a building company has been released by police.
The men forced entry into the maintenance firm in Saxon Close, Walthamstow, on March 13 at around 8.10pm.
It is understood three men forced the rear door to gain entry.
The thieves stole a 2014 grey Ford Transit van after finding a set of keys in the office.
Other items stolen included a Samsung tablet worth £300, a £300 HP laptop, and a Dewalt laser tool worth £200.
CCTV footage shows two of the men walking around the office.
One man, dressed in dark clothing and a light coloured hooded jacket, is seen picking up what appears to be the tablet or laptop and stuffing up his jacket.
Anyone with information is asked to contact police on 101 quoting 4905304/15 or Crimestoppers anonymously on 0800 555 111.
