But on November 14, 1906 Agras was seriously injured after an unsuccessful attack against the leader of the Bulgarian guerrilla troops, Apostol Petkov, near the village of Zervochori and was recalled to Thessaloniki to be healed.
The coordinator of the Greek forces, Konstantinos Mazarakis-Ainian, concerned for his life, ordered Agras to withdraw to Naoussa in April 1907, where he started recruiting locals to man the band of his substitute Captain Amyntas, alias Lieutenant Doumpiotis.
According to this version of events, despite Zlatan's opposition, Mucitano captured Agras and his ally Mingas and they were hanged on 7 June 1907 in an area between the villages of Techovo and Vladovon [el].
