Mohammad Iqbal, a director of the Ideal Home Builders Limited, was arrested at noon when he went to the Rajuk (Rajdhani Unnayan Kartripakkha) Bhaban in the city for official purposes.

Police said the Ideal Home Builders constructed a 16-storey residential-cum-commercial building in the Shantinagar area about two years ago without following the original design approved by the Rajuk, the sole authority to approve building plans and monitor construction.

It also sold all the apartments and spaces for shops.

But the buyers recently came to know that the developer did not follow the Rajuk-approved design. They lodged a complaint with the joint forces against the firm.

The joint forces arrested Iqbal from the Rajuk Bhaban and handed him over to the Paltan police.

Meanwhile, Mobarak Hossain, a Rajuk official, lodged a case against Iqbal with the Paltan Police Station yesterday.
