The men shown in these CCTV stills are being sought by police in connection with the robbery of a building society.
The three men, two of whom are believed to be in their teens, are wanted after cash was stolen from the Britannia Building Society in Edgware, north-west London, on Friday morning.
Two of the suspects jumped over the cashier's counter while the other stood by the front door.
A member of staff was pinned against the wall while money was grabbed.
All of the suspects, who are described as black and having London accents, then fled.
Anyone with information is asked to contact the Metropolitan Police on 020 8358 1752 or Crimestoppers anonymously on 0800 555 111.
