Thailand's state anti-corruption body has ruled that a former prime minister may have abused his power in overseeing a bloody crackdown on anti-government protesters in 2010, a decision that could lead to a 5-year ban from political office.

The National Anti-Corruption Commission said Tuesday that the actions of Abhisit Vejjajiva and then-Deputy Prime Minister Suthep Thaugsuban likely resulted in the deaths of civilians during two months of protests in which more than 90 people died and 2,000 were injured. The protesters were demanding new elections.

The commission will summon the two men to present their defense, and then decide whether to submit the case to the interim legislature — installed by the military after a coup last May — for a vote on impeachment that could impose the political ban.
