Smoke rises after serial bomb blasts took place at the venue of Narendra Modi's Hunkar rally in Patna.

There are conflicting reports about a man who managed to escape - with apparent ease - on Wednesday from the custody of the National Investigation Agency (NIA) and the country's top counter-terror agency. The man claimed to have crucial information about Sunday's serial blasts in Patna. He has reportedly been found on a train in Uttar Pradesh this evening.The National Investigating Agency or NIA claims that because Mehre Alam had not been formally arrested, it's incorrect to say that he escaped.Mehre Alam, according to the NIA, showed up in Patna and offered to help locate Haider Ali, who is allegedly a senior commander of the terror group Indian Mujahideen and is wanted for Sunday's blasts in which six people died and 83 were injured.He led investigators to a village where he said Haider Ali was hiding, but the search proved fruitless and on the way back, Mehre Alam, who was staying with members of the Bihar Police and the NIA at a lodge, excused himself to go to the toilet - and didn't return. The police then began searching for him.

The blasts on Sunday preceded a massive rally held in the capital by Narendra Modi, the BJP's candidate for Prime Minister. Six people are named in the First Information Report of FIR filed in the case. Two of them have been arrested. Among them is Imtiaz Ansari, the alleged mastermind. But Tehseen Akhtar, an alleged senior commander of the Indian Mujahideen and Haider Ali, who helped orchestrate the attack, are among the suspects who have not yet been found.
