Guwahati, Nov 17 (IANS): The law and order situation in troubled Kokrajhar district of Assam's Bodoland Territorial Areas Districts (BTAD) seems to be deteriorating further.

Suspected militants attacked a house in the district late Friday night, killing four persons - including a minor boy - on the spot, and injuring another minor boy.

The fresh incidents took place at Jiaguri village in the district, even though indefinite curfew remains in force in the district. The Army has been carrying out flag marches in all sensitive areas of the district for three days.

"A group of armed men sprayed bullets at the house of one Abbas Ali around 11 pm Friday, killing four people on the spot. Another minor boy received bullet injuries on his hand," said the police.

A woman who was injured after suspected militants opened indiscriminate fire at her house at Bamungaon in the district earlier Friday evening, succumbed to injuries at a local hospital Saturday morning.

With five deaths in the last 24 hours, the total death toll in violence in Kokrajhar district rose to 11. The turbulence here began Saturday last (Nov 10).

Meanwhile, Kokrajhar police have arrested Mono Kumar Brahma, executive member of the Bodoland Territorial Council, which runs the administration in the BTAD, Saturday. The arrest was made from his residence in Kokrajhar town, after illegal arms and ammunition were found in his possession.

A senior Assam Police official confirmed the arrest of Brahma and said that the police have also seized two AK 47 rifles, two magazines and 60 rounds of live ammunition from him.

Brahma is a member of the Bodoland Peoples Front (BPF), which is in power in the Bodoland Territorial Council and also a partner with the ruling Congress in Assam.

"Brahma is being questioned by our officers over his alleged role in the fresh violence and over the possession of illegal arms from his residence," said the official.

The arrest and seizure of illegal arms and ammunition came in less than 24 hours after the Assam DGP J.N. Choudhury visited Kokrajhar, and asked forces to intensify operations against illegal arms and ammunition.

The DGP, who had visited Kokrajhar on Friday, had also said that illegal arms and ammunition - which the BTAD allegedly stocks in huge quantities - is a big concern for forces deployed to contain violence in Kokrajhar.
