Venezuelan opposition leader Henrique Capriles said it was only the intervention of a group of motorcyclists that prevented unidentified assailants from setting fire to his vehicle in the western city of Maracay.
"They tried to set fire to our vehicle when we were going to Maracay!" the governor of Miranda state said on Twitter.
Defeated in last April's presidential elections, Capriles heads the electoral campaign for candidates of the MUD opposition alliance in the Dec. 8 municipal elections.
Capriles accused President Nicolas Maduro a week ago of trying to keep him from supporting MUD candidates by making air travel around the country extremely difficult for him, after several incidents on his flights.
Maduro announced last Friday that he had ordered the capture of "two operators" of MUD-affiliated parties, who, he said, "were detected trying to contract motorcyclists, dress them in red and have them attack" opposition politicians.
Red is the color of Venezuela's governing leftist PSUV party.
Capriles was denounced Monday by the governor of the western state of Tachira, Maduro ally Jose Vielma, for seeking to foment political violence in the region. EFE
