The Mumbai Police detained several men for questioning . One of those detained — Faiz Usmani — died while in police custody on 17 July , sparking allegations of police brutality . Usmani was the brother of one of the accused in the 2008 Ahmedabad bombings case . It was alleged by his family members that Faiz Usmani was healthy when the police picked him up and that he was subjected to torture in police custody . The police dismissed these charges and countered that Usmani was suffering from hypertension and complained of giddiness after walking himself into a police station . He was admitted to the Lokmanya Tilak hospital , Sion , Mumbai , following which he died quickly due to blood clots in brain and a heart attack . A CID probe has been ordered into Usmani 's death
