A key suspect in the serial blasts in the eastern Indian city Patna has been re-arrested after escaping from police, said local media Friday. Terror suspect Meher Alam, accused of involvement in Sunday's Patna serial blasts and who escaped from the custody of the National Investigation Agency of India, was arrested in the northern state Uttar Pradesh's Kanpur city late Thursday, said Indo-Asian News Service. Alam, 25, was one of the suspects in the string of bombings that took place in Patna, state capital of Bihar, when opposition Bharatiya Janata Party (BJP)'s prime ministerial candidate Narendra Modi was addressing a huge rally. He escaped late Wednesday from police custody in Bihar's Muzaffarpur city. Six people were killed and over 80 injured in Sunday's serial attacks in Patna. Indian police said home-grown militant group Indian Mujahideen had masterminded the attack.
