This is the moment a masked gang armed with a shotgun and crowbars smashed their way into a house in east London during a terrifying burglary.

Three people in their 20s and early 30s were at home when the gang drove up to the house in Wallenger Avenue, Romford – two of them arriving in a black convertible Porsche – and forced their way inside.

The shocking CCTV footage was released today by detectives hunting the four men.

In the clip, one of them jumps out of the sports car and rushes over to a CCTV camera with a crowbar before smashing it to pieces.

The camera filmed an expensive-looking watch on his wrist before cutting out.

A second camera recorded one of his accomplices pulling a shotgun from the front of the Porsche, before the pair are joined by two more men who are believed to have arrived in a black Mercedes.

The gang then batter the front door down by kicking it and hitting it with their crowbars.

Police said the three people in the house suffered minor injuries from the breaking glass.

The suspects stole two watches and made off in the Porsche and a black Mercedes, police said.

Anyone with information about the incident or who can identify any of the men should call Havering CID on 101 or Crimestoppers anonymously on 0800 555 111.
