A robbery took place at the Piraeus Bank branch located at 27-31 Hatzikyriakou Street, in Kallipolis, Piraeus.
Four armed men wearing masks entered the bank at approximately 2 p.m. and held up five bank employees and three clients who were inside the branch at the time. The robbers threatened the hostages with a grenade and then proceeded to the lower level of the bank searching for money and gold.
According to reports, the perpetrators used oxygen to break the doors and worked there for 2.5 hours. After extracting an unknown amount of money and jewels, they escaped by unknown means.
Police said they were alerted at 4:39 p.m. after an emergency button was activated and a few minutes later they arrived at the scene; by that time the robbers had already disappeared.
A similar robbery took place at another branch of the same bank on Kifissias Avenue in Ambelokipi back in August 2016.
Greek police have launched an investigation and manhunt to find the four perpetrators.
