Assam's Education Minister Ripun Borah, a suspect in murder of his political rival in 2000, was on Tuesday arrested by the CBI for allegedly offering a bribe of Rs 10 lakh to an agency official to hush up the case.
The CBI official, probing the murder of student leader Daniel Toppo, filed a complaint on Monday evening that the Minister had allegedly offered him a bribe.
A case was filed in the designated court against the Minister and his associate Mukul Pathak after which a trap was laid to arrest Borah.
Borah was arrested from Mathura Road in south Delhi when he was allegedly offering the bribe to the official.
Toppo, district president of All Assam Tea Tribe Students Union, was Borah's rival candidate during the 1996 assembly polls.
The CBI was handed over the investigation into the case in 2001 after the Assam Police could not make any breakthrough into the murder that took place on September 27, 2000.
Immediately after Borah's arrest, Pathak, who was travelling from Delhi to Guwahati, was taken into custody at the Delhi airport itself.
Borah, who had a long innings as Assam Pradesh Congress Committee spokesman, is a suspect in the murder case and had been questioned several times by the CBI.
The Minister is claimed to have approached the CBI officer through the middleman for negotiating the outcome of the investigation into the murder case.
The CBI registered a case under section 120-B (criminal conspiracy) of Indian Penal Code and relevant sections of the Prevention of Corruption Act.
Reacting to Borah's arrest, Assam Chief Minister Tarun Gogoi said "law will take its own course".
