Police and BSF were already on heightened alert. They are gearing up for this new threat. According to the SIB's information, the group set off from their hideout in Bangladesh on Dec 15. They had taken shelter in the house of Haider Ali, a Jama'atul Mujahideen Bangladesh (JMB) activist of Bangar, in the Ranisankhoil area of north Bangladesh.
Intelligence agents have learnt that the group paid Rs 2000 as rent per day for their stay in Haidar's house. Two HuJI leaders from Pakistan — S K Alimuddin Quraishi (40) and S K Jaimuddin Ali (45) — apparently led the group from Ranisankhoil to help them cross the border.
There were reports that they were carrying a considerable amount of fake cash, arms and ammunition and set out with the plan to cross the border at Maheshgaon or Hemtabad, near Raigunj in North Dinajpur.
Four members of the squad have been identified KLO militants Sheikh Naimuddin (25) and B Singha (27) and HuJI operatives Sabbir Hussain (30) and Nasir Ali (25), apart from Quraishi and Jaimuddin,
"The names of the others in the group has not been ascertained yet," says the note sent by IB to the state government.
The group is learnt to have started from Ranisankhoil at 3.15 pm on Dec 15, and are believed to have reached the India-Bangladesh border that evening. No trace of them was found after that.
This ties up with intelligence inputs soon after the Mumbai terror strike that HuJI-KLO teams might have entered Bengal armed with RDX. Intelligence sources have revealed that a group of over 30 HuJI and KLO members had entered Bengal through three different locations — one crossed the North Bengal border while two others entered from south Bengal.
These groups are 'consistently' planning attacks in Kolkata and another location in south Bengal, and even in Siliguri and New Jalpaiguri, say sources.
