Around 9.40 a.m., police were summoned to the site of a third heist, at a Eurobank branch on the corner of Poseidonos and Afxentiou streets in the southern suburb of Alimos, from which two gunmen stole 12,000 euros. The last robbery of the day was at an Alpha Bank branch at 46 Veikou St in Kypseli, from which two men took 6,000 euros.
