On 12 May 2018, Cyril Almeida published an interview of the former prime minister Nawaz Sharif, where Sharif is reported to have said, in connection with the trial of the accused in the 2008 Mumbai attacks:
"Militant organizations are active. Call them non-state actors, should we allow them to cross the border and kill 150 people in Mumbai? Explain it to me. Why can’t we complete the trial?"
After the interview was published, the Pakistan Press Council issued a notice to Dawn stating that it published information that "may bring into contempt Pakistan or its people or tends to undermine its sovereignty or integrity as an independent country." The distribution of the newspaper was subsequently blocked in parts of the country. Scholar Madiha Afzal states that the Pakistani military was behind the efforts of censorship.
In September 2018, Azhar Siddiqui, a lawyer, petitioned the Lahore High Court, accusing Nawaz Sharif and former prime minister Shahid Khaqan Abbasi of treason. He alleged that Abbasi had leaked the minutes of the National Security Council to Sharif, whose statement contained such information. Almeida was asked to appear before the court and, when he failed to appear in three sittings, a non-bailable arrest warrant was issued against him. He was also placed on the Exit Control List, banning travel abroad. It was unclear whether the treason charges also applied to Almeida.
