A bombing suspect arrested after the serial blasts that hit the eastern Indian city Patna last Sunday has died of the injuries he suffered when he was planting the bomb at the railway station's public toilet, said police. "Ainul alias Tarique died due to his injuries at a hospital in Patna, late Thursday night," said a police officer. Before his identity was disclosed by the police, he was believed to be a victim. Earlier police reports said another suspect died of injuries but the man turned out to be a victim of the blasts, which took place when Indian opposition Bharatiya Janata Party prime ministerial candidate Narendra Modi was addressing a huge rally of supporters in Patna. Six people were killed and 83 injured in seven bomb blasts in Patna. Indian police said home-grown militant group Indian Mujahideen was behind the attack and they have arrested at least two other suspects.
