Police are investigating a mysterious incident in Brighton, in which four men called at an address looking for someone who does not live there - armed with metal bars and a baseball bat.
Officers were called out at 10.25pm last night to the address in Pett Close, Whitehawk.
The men had forced a door and were shouting threats to a man, but nobody of that name lives there.
On realising that the men left and are believed to have driven away in a silver hatchback vehicle. Nobody was injured and nothing was taken.
We're keen to trace any further witnesses and in particular any details of the vehicle.
"The people at the flat, a 31-year old woman who is heavily pregnant, a 32-year old man and two children aged 6 and 11, although unhurt, were shaken by what happened.
"Our enquiries are at an early stage and an exact motive for this incident not yet been established, but it is already clear that they have no connection with the man whose name was shouted.
"If you can help please call us on 101 quoting serial 1746 of 10/10. You can also call independent charity Crimestoppers anonymously on 0800 555 11."
