Berlin Bank Heist Tunnel Pictures Released

Police in Berlin have released pictures of a 100ft tunnel dug by robbers from an underground car park into a bank's safe deposit room.

Police have also issued a composite sketch of a man suspected of involvement in the digging of the tunnel.

The audacious criminals spent weeks digging the tunnel into a vault of the Berliner Volksbank and, earlier in the week, escaped with the contents of several hundred safety deposit boxes.

They set fire to the tunnel as they left to destroy any evidence.

Police were alerted to the break-in early on Monday when a security guard noticed smoke coming from the deposit room.

Berlin police spokesman Thomas Neuendorf said at the time of the discovery that the tunnel was "very professional" and must have taken weeks or possibly months to complete.

It was elaborately constructed and even had ceiling supports.

Mr Neuendorf said officers were still trying to determine what valuables had been stolen from the deposit boxes.
