IndyCar: More Twitter trouble for Castroneves

Helio Castroneves has drawn the ire of Verizon IndyCar Series officials for a post-race tweet from Long Beach and has been placed on probation through June 30, 2014.

"Indycar officials continuing not punishing some drivers and giving green flag during an accident," the missive read. The three-time Indy 500 winner later attributed the tweet to his sister and deleted it from his account.

This marks the latest social media faux pas by the veteran.

Castroneves was fined $30,000 and placed on probation in 2011 after IndyCar's final race at Motegi in Japan when he took to Twitter to blast former chief steward Brian Barnhart.

A late-race waving yellow flag for the stranded car of Vitor Meira in Turn 3 led Barnhart to instruct drivers not to pass in that area, yet Castroneves, locked in a battle with JR Hildebrand for seventh place, overtook the rookie on the outside of the corner—closest to Meira's car—and was later demoted to 22nd place, the final car on the lead lap, for the infraction.

The Team Penske driver vented his frustrations once he learned of the adjusted race results.

"It is sad to see one person being responsible for bringing down an entire series," he wrote. "Brian Banhart is inconsistent and even changes rule book when is convenient for him, and his own personal interests. In the same race in International television he penalizes some but not others. Making the famous @paultracy 's words mine : Brian Barnhart is a circus clown! Very disappointed for finishing 7th. and being put to 22nd. This is just ABSURD !!! Just expressing my feelings right now!"
