Gruev's activities in the Bitola district were not left unnoticed by the Ottoman authorities. Numerous chetas (bands) throughout the surrounding mountains began to terrorize the local authorities. Gruev, being suspected as a major factor in fostering this movement, was arrested on 6 August 1900. He was held in Bitola jail until May 1902.
