In December 2023, Khaled Mabrouki was arrested following a dispute with one of his neighbors. He was referred to court and sentenced to one year of imprisonment at Bork Erroumi Civil Prison.

At the beginning of his detention, his family submitted his medical file to the prison administration and to the Citizen Relations Office, confirming that he suffered from psychological disorders requiring medical follow-up and treatment. They were informed that a large number of detainees were awaiting medical examination.

During his detention, his psychological condition significantly worsened without him receiving the necessary medical or psychological care, according to his family. His family also stated that Khaled repeatedly reported being subjected to physical violence by prison officers. He frequently expressed severe suffering and stated that the conditions of detention were harsh and that imprisonment had exhausted him physically and psychologically.

In December 2024, Khaled Mabrouki was released from prison. His mother noticed visible blue bruises on his back, indicating that he had been subjected to physical violence during his detention. After his release, he continued to suffer from psychological distress resulting from his experience in prison and did not receive appropriate medical follow-up.

On April 29, 2025, Khaled Mabrouki set himself on fire and died at the scene.
