STOCKHOLM – A senior Swedish prosecutor reopened a rape investigation against WikiLeaks founder Julian Assange on Wednesday, the latest twist to a puzzling case in which prosecutors of different ranks have overruled each other.

Assange has denied the allegations and suggested they are part of a smear campaign by opponents of WikiLeaks – an online whistle-blower that has angered Washington by publishing thousands of leaked documents about U.S. military activities in Iraq and Afghanistan.

The case was dismissed last week by Eva Finne, chief prosecutor in Stockholm, who overruled a lower-ranked prosecutor and said there was no reason to suspect that Assange, an Australian citizen, had raped a Swedish woman who had reported him to police.

The woman’s lawyer appealed the decision. Director of Public Prosecution Marianne Ny decided to reopen the case Wednesday, saying new information had come in on Tuesday.

“We went through all the case material again, including what came in, and that’s when I made my decision,” to reopen the case, Ny told The Associated Press by phone.

She declined to say what new information she had received or whether Assange, who was questioned by investigators on Monday, would be arrested.

An arrest warrant issued Aug. 20 was withdrawn within 24 hours amid the back-and-forth between prosecutors.

Ny said “it’s not entirely uncommon” that such reversals take place in Sweden, in particular regarding allegations of sex crimes.

Ny also decided that another complaint against Assange should be investigated on suspicion of “sexual coercion and sexual molestation.” That overruled a previous decision to only investigate the case as “molestation,” which is not a sex offense under Swedish law.

Investigators have not released details about either case.
