Security forces in a drive seized four arms and ammunition from a criminals' hideout in Alikadam upazilla of the district yesterday morning.
Other recovered items are four cartridges, four mobile phone sets, one set of olive coloured military uniform, one national identity card of a Bangladeshi national, two rubber stamps and some cash money.
Acting on a tip off, a special team of Alikadam army zone led by its commander Lt Col Faizur Rahaman started the operation at Ailang Mroopara, about 8km away from the upazila, on Tuesday night.
At one stage of the drive, they found the hideout in a Jhum house (temporary house in hilly paddy field) early morning. Sensing presence of the forces, the miscreants fled the scene. Later, they recovered the arms and ammunition and other items kept in the house, official sources said.
The ID card belongs to Smriti Chakma of Panchhari upazila in Khagrachhari district while two rubber stamps belonged to Baishari union parishad chairman in Naikhangchhari upazila of Bandarban district and Dr Ahasanul Hoque of Chittagong Medical College Hospital, Chittagong.
Security forces suspected that at least four criminals had taken shelter in the house and they might have been involved in abduction of Naikhangchhari PHP rubber garden supervisor Hefajetur Rahaman.
Hefajet was abducted on August 16 and he was set free at Alikadam on August 24.
