The explosion occurred outside the Vaghzari polling booth in the Etapalli sub-division where a few people were queued for exercising their franchise for the Gadchiroli-Chimur Lok Sabha seat.
The blast was described as "minor" and despite the initial panic, voting continued peacefully.
On Wednesday evening, an IED blast, allegedly triggered by Maoists, had injured two troopers of the Central Reserve Police Force who were proceedings on election security duties.
In view of the two blasts, security was further tightened in the entire district which went to the polls on Thursday along with six others in eastern Maharashtra.
