He was eventually traced to Pune and brought back to Mumbai where he went through a medical examination. He was eventually diagnosed with a mental disorder, and his brother Aamir and his father were in a custody battle over Faisal that garnered much press coverage. Faisal's custody was awarded to his father, Tahir.
