The location of United Liberation Front of Asom chief Arabinda Rajkhowa and the outfit's military deputy-in-chief Raju Barua besides eight others apprehended by the Assam police is being kept a closely guarded secret.
There were reports that Rajkhowa and the others were shifted from the high-security 4th Assam police battalion establishment at Kahilipara to another location in Guwahati, but police officials were unwilling to part with any information on his exact location.
Rajkhowa, along with his wife and nine others had arrived in Guwahati on Friday after they were handed over to the Border Security Force by Bangladesh security forces at Dawki in Meghalaya.
Rajkhowa and Barua are expected to be produced in the Kamrup chief judicial magistrate court at any time, his lawyer who practises in the Gauhati high court, Bijon Mahajan said.
"As Rajkhowa and Barua's family members have appointed me as their lawyer, it will be my duty to ensure that they get justice under the law of the land," he said.
Asked under what act they could be arrested, the lawyer said it could be under the Special Operations Unit (SOU) 2/98 or other similar act if their names figured in the police records.
Unprecedented security measures were evident around the CJM court in Pan Bazar with a huge number of police and paramilitary forces deployed.
A barricade has been erected near the court, while traffic in the area was diverted.
