Mohamed Guefassa, a 23-year-old Algerian from the region of Wilaya d'El Tarf, was arrested while trying to reach Sardinia by boat on October 2, 2016. He and 15 other individuals were intercepted in Tunisian territorial waters after having left Algeria.  

Tunisian fishermen who witnessed the arrest informed Guefassa’s brother about what had happened, saying that the group was transferred to Tunisia and incarcerated. Two months later, the families received phone calls from their missing relatives confirming that they were detained in Tunisia.
