The key accused of the October 2 Burdwan blast, that left two dead, gave a slip to the West Bengal Police as well as to the National Investigation Agency and are believed to have fled to Bangladesh, official sources said.
The team's visit is tentatively fixed for November 9 and 10 and a senior officer of the NIA in the rank of Inspector General of Police will lead it, the sources said.
Sources privy to the investigation said no substantial evidence has come there way about the terror plot of the group, which is stated to be targeting Bangladesh government leaders.
On October two, the blast took place inside a house at Khagragarh in Burdwan in which suspected terrorist Shakil Ahmed died on the spot while his associate Sovan Mandal died in hospital.
