The International Monetary Fund said Dominique Strauss-Kahn has resigned as its head following charges against him of sexual assault and attempted rape.

“I deny with the greatest possible firmness all of the allegations that have been made against me,” Strauss-Kahn said in his letter of resignation, which was released by the IMF and dated May 18.

“I want to devote all my strength, all my time, and all my energy to proving my innocence.”

He will on Thursday for a second time request release on $1 million cash bail and placement under 24-hour house arrest while he awaits trial on charges of attempting to rape a hotel maid, his lawyers said. He is being held in New York’s notorious Rikers Island jail.

“Yes there will definitely be a bail hearing tomorrow,” Manhattan District Attorney’s Office spokeswoman Erin Duggan told Reuters on Wednesday.
