Investigators and top detectives claimed that they have found some 'interesting information', which they refused to disclose for the sake of investigation.

Commissioner of Dhaka Metropolitan Police Ashraful Huda said no significant progress could be achieved in the investigation.

He hoped that the source and destination of the firearms and identity of the gunrunners would be known once the lone arrested gunrunner, Abdul Aziz, was interrogated.

Police said Aziz, now under treatment at the Combined Military Hospital after being critically injured during the Sunday morning raid and gunfight, is still not fit for interrogation.

Following the seizure of the arms, police and members of other law enforcing agencies started manhunt in Kuril Budda and Mohammadpur areas by slapping curfew on Monday and Tuesday nights. In two days, 94 people were arrested, but no-one was found linked to the arms cache.

Police are still trying to arrest Lincoln, who is one of the prime suspects in the case. Another suspect, Manik, owner of a signboard shop from where the arms were seized, said Lincoln took the key of his shop in the same afternoon from him.

Four AK-47 assault rifles, two revolvers, 20 hand grenades, four time bombs, a large number of AK-47 ammunition and other explosives were seized among other things from the signboard shop during a predawn raid on Sunday on the signboard shop.
