"We are yet to get any information (about the gunrunning)," Commissioner of Dhaka Metropolitan Police (DMP) Ashraful Huda said last night. "We hope to make progress after interrogating the criminal, Abdul Aziz, who was arrested injured on the spot."

Aziz is still undergoing treatment at the Combined Military Hospital. Two policemen -- Sub-inspector (SI) Saidur Rahman and Constable Neyamat Ali -- who were also wounded in the gunfight with the criminals during the raid are also being treated there.

Four AK-47 rifles, 990 rounds of bullets, two foreign-made revolvers, seven revolver bullets, 20 hand grenades, two 2-kg plastic explosive bombs, four time bombs, half a kilogram of gunpowder, six electric detonators, four-and- a-half yard detonation wire, two firing devices with charger, two time devices and a walkie-talkie were seized from a signboard shop at Kuril Badda after a gunfight between a patrol team of Badda police and the racket at around 4:00am Sunday.

The Detective Branch (DB) of police has been assigned to investigate the arms haul.

Joint forces of police and paramilitary Bangladesh Rifles (BDR) picked up 38 persons from Kuril Badda area during a four-hour curfew beginning at zero hours yesterday. But no-one could be linked to the gunrunning. Twenty-one of them were shown arrested and produced before court.

"We are checking if the 21 arrestees have any criminal records," said Golam Rasul, deputy commissioner of police (north zone).

Badda police sources said plainclothes and uniformed law enforcers are still stationed at different points.

Rasul said hunt is on for one Lincoln of Ashkona in Uttara, who, he believes, carted the arms to the shop. "He is an identified drug smuggler and involved in the gunrunning."

It was learnt that Lincoln has hideouts at Tongi Board Bazar and nearby areas.

"We have already raided these places but could not find him," Rasul said.

Meanwhile, Mehedi Hasan Manik, owner of Tulir Parash, the signboard shop from where the arms and ammunition were recovered, was placed on a seven-day remand yesterday.

DB Inspector Sirajul Islam, who is probing the case, produced Manik before the Court of Chief Metropolitan Magistrate yesterday.

In his remand petition, the inspector said Manik knows if more arms are kept hidden and he needs to be quizzed to solve the case.

Denying his involvement in the gunrunning, Manik told police Lincoln took the key of his shop on Saturday afternoon saying he would stay there because he had quarelled with his parents. Lincoln remained inside the shop at least till 8:00pm, Manik said.
