Two owners of garment factories in the building that collapsed on the outskirts of the Bangladeshi capital Dhaka have surrendered to police.

Mahbubur Rahman Tapas and Balzul Samad Adnan are suspected of forcing staff to work in the eight-storey building, ignoring warnings about cracks.

More than 330 people are known to have died after the Rana Plaza in the suburb of Savar collapsed on Wednesday.

On Saturday morning, at least 24 more people were rescued from the rubble.
