Sk Kausar, the prime accused in the Bardhaman blast, may have escaped to Bangladesh via Hakimpur bordering Nadia and North 24-Parganas.
Quoting Indian CID officers, the Times of India reported on Sunday.
Kausar had travelled nearly 100 kilometres before he sneaked into Bangladesh, the report said, adding the investigators have also reconstructed the escape route.
According to CID, Kauser left the spot immediately after the blast, but he didn't leave the plce till the next day.
CID officers have reasons to believe that the terrorist stayed in a lodge at Bhatar, just 23 kilometres from Burdwan town, TOI report said.
He decamped after getting to know about the blast from Amina Bibi, now in custody, over phone.
The investigating officers, after speaking to the locals, are sure that he left his bike at Khetia village — 10 kilometres from Bardhaman.
"We have come to know that he took one person and rode off, but the locals failed to identify them as they were wearing helmets.
At this stage, we cannot tell with certainty whether the man who was pillion riding with Kausar came back to the village or left for somewhere else," a CID officer said.
The officers said from Khetia, Kausar travelled another 13 kilometres to reach Bhatar and stayed there in a lodge overnight.
The CID officers have zeroed in on one hotelier from whom they came to know that Kausar stayed in a lodge for the night but they are not sure how he travelled from Khetia to Bhatar.
The next morning — October 3 — he took the Bardhaman-Katwa road that touches NH34 and reached Krishnagar.
"His mode of escape shows he is seasoned. He didn't leave on the same day but wanted to observe the development. Secondly, he could have taken a shorter route via Dhatrigram from where Krishnagar is just 34 kilometres. Instead, he took a detour to reach Krishnagar via Bhatar. Kausar took the safest route to cross the border through Hakimpur which is another 47 kilometres from Krishnagar," an investigating officer said.
However, the CID officers are not sure about the exact day he crossed the border.
But, they believe that he had at least five facilitators who arranged the logistics for a safe transit.
