In June 1871 Obshti was sent to Ottoman Bulgaria to serve as Levski's first deputy but compromised his superior's efforts by his adventurous endeavours.

Against the opinion of Levski, in September 1872 Obshti organized the robbery of the Ottoman postal convoy in the Arabakonak Pass in order to fund the BRCC activities.

[3] The Ottoman authorities reacted harshly and managed to arrest a number of BRCC militants, including Obshti and Levski.

[4] Obshti grasped at the chance to publicize the BRCC activities in order to arouse the Great Powers' interest in liberating Bulgaria.

He made some revealing statements in court which led to a great number of arrests and the effective ruin of the clandestine network.
