The incident came just three days before Georgia's parliamentary elections.
Reports from the Georgian capital say lawmaker Givi Targamadze from the United National Movement (ENM) was not hurt by the October 4 blast.
Targamadze was seated in the front seat next to his driver when the blast occurred. His driver also escaped injury.
But two people on the street nearby were hospitalized and three other were slightly injured.
The United National Movement is Georgia's largest opposition party.
On October 2, two men were shot and wounded during an open-air campaign speech given by independent candidate and former Defense Minister Irakly Okruashvili in the town of Gori.
