Anas Altikriti was in London, and busy, on the day in July 2020 when his phone was hacked. He frequently works as a hostage negotiator and, at the time, he was negotiating a deal to free a hostage being held on the Libya–Chad border. Altikriti also had a meeting with former Labour Party leader Jeremy Corbyn. But his schedule did not include having his phone infiltrated by Pegasus, the phone hacking software made by Israel’s NSO Group.

For many years, he had been vocally critical of the UAE, where he previously lived. The UAE designated his organization, the Cordoba Foundation — which works to promote dialogue and rapprochement between Islam and the West — as a terrorist group in 2014. In response, the organization issued a statement calling the country a “despotic regime seeking to silence any form of dissent.” He made similar declarations about the UAE over the following years.

Four years later, Altikriti, an Iraqi-born British citizen and vocal critic of the United Arab Emirates, is filing a report to the Metropolitan Police in London accusing the Israeli spyware firm NSO Group of complicity in the targeted hacking of his phone. On Wednesday, he filed the complaint about NSO and its associates alongside three fellow U.K.-based human rights defenders whose phones were also hacked.

Assembled with the help of advocates from GLAN on behalf of the victims, the extensively footnoted filing sent to the Metropolitan Police, which was obtained by The Intercept, puts the ball in the police’s court. The police now have discretion over whether to open an investigation and subsequently bring charges.
