The Tiger Squad also reportedly killed Suleiman Abdul Rahman al-Thuniyan, a Saudi court judge who was murdered by injection of deadly virus into his body when he had visited a hospital for a regular health checkup. "One of the techniques the tiger squad uses to silence dissidents or opponents of the government is to 'kill them with HIV, or other sorts of deadly viruses'".[1] However, some sources have stated that al-Thuniyan died after he suffered from a chronic disease.[10]
