The Supreme Judicial Council appointed him as the forensic investigator in the Beirut Port bombing that took place on August 4, 2020. However, In February 2020, the Lebanese court removed him from his of position, following legal challenges by Lebanese officials who he had previously accused of the "negligence" that led to the blast. The move, which is believed to be planned on purpose, will further delay the investigation that had already faced violent political opposition. He also faced criticism from the Shiite Hezbollah and the Sunni former Prime Minister Saad Hariri. He was removed from the case on February 18, 2021, after the request from 2 ex-ministers Ghazi Zeaiter and Ali Hassan Khalil, both lawmakers for the speaker Nabih Berri's Amal Movement, the ally of Hezbollah, the two he had already charged in the case, a move condemned by the Human Rights Watch.
