Attorney Michael Avenatti was arrested Tuesday for allegedly violating terms of his pretrial release.

Avenatti, who was arrested about 6 p.m. following a state bar hearing considering whether to place him on an inactive attorney list, is expected to appear before U.S. District Judge James Selna Wednesday morning, Avenatti’s attorney, Dean Steward, said.

Avenatti was arrested by Internal Revenue Service agents, but further details on the allegations against him were under seal, said Thom Mrozek, director of media relations for the U.S. Attorney’s Office.

Avenatti is expected to soon go on trial in New York for allegedly attempting to extort $25 million from Nike with threats to expose alleged payments by the shoe company in the recruitment of college basketball players.

Avenatti was indicted in April for allegedly defrauding clients and failing to pay personal taxes, as well as payroll and other taxes from his ownership of a coffee shop business. Before he was indicted, Avenatti agreed in a bankruptcy proceeding to turn over property from Eagan Avenatti LLP.
