Guwahati, April 12: A top gun of the banned People’s Revolutionary Party of Kangleipak (Prepak) was captured in Guwahati last night, continuing a sequence of arrests that began in Imphal last weekend and extended to Calcutta a day later.

The Guwahati leg of the crackdown on the outlawed Prepak’s expansive network also yielded three activists of another Manipur-based militant group, the People’s United Liberation Front.

Additional superintendent of police Rajen Singh said the rebels were apprehended during a joint operation by city police along with their Manipur counterparts.

They were traced to different areas of Guwahati.

The Prepak member, 34-year-old H. Iboyaima Singh alias James, is from Singjamei in Imphal West. He is suspected to have been camping in the city to arrange for medical treatment of Prepak members.

The arrested PULF members are “finance secretary” Nasir Khan alias Nawab from Tarahei in Imphal East, “convener” Abdul Noor alias Danish of Imphal West and Abdul Razzak of Liling in Thoubal. Like James, all three are in their early thirties and came to the city about a month ago. They were involved in extortion, the police said.

The rebels were produced in a city court today before the Manipur police team took them to Imphal. Another team from Manipur is in Calcutta to take custody of the two Prepak militants arrested there on Sunday. Rakesh Singh and R.K. Dhaneshwar were staying in Calcutta to teach a group of 15 students of Jadavpur University how to execute guerrilla attacks on security forces.

Military Intelligence traced Rakesh and Dhaneshwar on the basis of information provided by Sanjay Singh and Leishram Ibobi Singh, two top leaders of the organisation who spent six months in a rented house at Jadavpur in Calcutta, masquerading as university students.

Sanjay and Leishram were arrested at Imphal airport when they landed there from Calcutta on April 7.

A police officer said James’s arrest was as big a blow to Prepak as the previous setbacks.

Intelligence agencies say members of several armed groups of the Northeast have been using Guwahati as a base to co-ordinate various activities.
