The fugitive owner of an illegally constructed building that collapsed in a deadly heap in Bangladesh last week was captured in an alleged attempt to escape to India.
Mohammed Sohel Rana was arrested on Sunday in Benapole in western Bangladesh, just as he was about to flee into India's West Bengal state.
Rana had the approval to construct five floors but he added three more illegally.
On Saturday, police took six people into custody, including three owners of two factories.
Also under detention are the wife of the building owner who is on the run and two government engineers who were involved in giving approval for the building design.
Among those arrested are Bazlus Samad, managing director of New Wave Apparels Ltd, and Mahmudur Rahman Tapash, the company chairman, and Aminul Islam, chairman of Phantom Apparels Ltd.
Rana was a local leader of ruling Awami League's youth front.
His arrest, and that of the factory owners, was ordered by Prime Minister Sheikh Hasina, who is also the Awami League leader.
