The authorities in Bangladesh on Sunday raided the office of a global Islamic terror group and seized key documents amid fears that terrorists were trying to regroup in the country, a news report said.
Police seized equipment and materials from the Dhaka head office of Islamic outfit Hizb-ut-Tahrir, which was banned on October 22 by the government as it was a "threat to national safety".
Mahid Uddin, Deputy Police commissioner of Motijheel zone in the capital, said the "papers seized from the office shows that they were very well organised."
A computer, files and a video camera were seized in the raid, but the crucial hard disk of the computer was not found, the police said.
"The stuffs were seized following a court a order," Mujibur Rahman, officer in charge of Paltan Police Station, was quoted as saying by the Daily Star newspaper on Sunday.
According to the authorities the organisation has been banned in a number of countries, "including Turkey because of their involvement with terrorist activities".
The outfit is the fifth militant organisation to be banned in Bangladesh. Amid earlier warning that Islamaist militants may be trying to regroup, the police and paramilitary forces conducted massive anti-militancy operations across the country.
