An Egyptian filmmaker detained without trial for over two years for making a music video that mocked President Abdel Fattah al-Sisi died on Saturday at a maximum-security prison complex, two rights lawyers said.

Attorney Ahmed el-Khwaga said his 22-year-old client Shady Habash died in Cairo’s Tora Prison complex. He said the cause of death was not immediately clear.

There was no immediate comment from the Interior Ministry, which oversees Egypt’s prison system.

Police forces arrested the young filmmaker in March 2018 after he directed a music video by Ramy Essam, an Egyptian musician exiled in Sweden. The video featured a song that mocked the general-turned president, comparing him to a fruit date and condemning alleged government corruption.

Khaled Ali, a rights lawyer, said Habash should have been released two months ago after serving the maximum jail time during pending investigations.
