BRASILIA, Feb 8 (Reuters) - Brazil’s federal police on Thursday sought to confiscate former President Jair Bolsonaro’s passport and arrest some of his closest aides, sources said, as part of an investigation into an alleged coup attempt after he lost the 2022 election.

The operation reflects a tightening net around Bolsonaro, his family and some of his most powerful allies for actions before and after his unsuccessful reelection effort. The confiscation of his passport will be especially worrying for the former president, a far-right firebrand who cast himself as a Brazilian version of former U.S. President Donald Trump.
