The residents of Rangamatty Goan blocked a mini-truck, carrying six cows and bulls by an alleged five-member cattle theft gang, in the wee hours and caught hold of its driver Junti Ali as four others fled from the spot, police officials said.
The driver's legs and one hand were chopped by the mob which led to his death, after which they kept the body on NH-37, police said.
Golaghat Superintendent of Police P P Singh intervened and assured the locals of arresting the culprits, bringing the situation under control.
The locals recovered six cows and bulls which they later handed over to their respective owners, the officials said.
