The team headed by Deputy Inspector General (Special Branch) Khagen Sarma will bring Gogoi here after interrogation at the end of his police custody period on April 21, the sources added.

Calcutta chief metropolitan magistrate D Paul had remanded Gogoi to Calcutta police custody till April 21 when the United Liberation Front of Assam leader was produced before him on April 9.

The sources said that Calcutta police had recovered a list of telephone numbers, including some mobile phone numbers, a personal letter from one Arati, some metro railway tickets and Rs 391 in cash.

Gogoi, second in the hierarchy of the outlawed militant group, was arrested in a joint operation by the Calcutta and Assam police and the Army from a hotel in Calcutta's New Market area.

Gogoi's arrest camejust four months after the arrest of ULFA general secretary Anup Chetia in Dhaka.

Meanwhile, a report from Siliguri has said that a suspected ULFA link and lorry driver of a local transport firm Shyam Kumar Gupta, who was in police custody, tried to commit suicide inside his cell yesterday by slashing his throat and pulse veins.

Police said Gupta was arrested on Thursday following a complaint by his employer Santosh Kumar Goel, who had received an extortion letter from United Liberation Front of Assam demanding that he hand over Rs one lakh to the driver, police said.

Following the suicide attempt, Gupta was shifted to a local private hospital in an unconscious state. Hospital authorities reported no change in Gupta's condition today.
