Police in Taiwan are questioning the developer of a building which collapsed in Saturday's earthquake.
At least 39 people inside the Weiguan Jinlong (Golden Dragon) apartment complex in Tainan were killed when it collapsed. Two others died elsewhere.
About 320 people have been rescued but more than 100 people may still be trapped under the debris.
It was one of the few buildings to suffer serious damage, prompting an investigation into how it was built.
With hopes fading of finding more survivors, rescuers are now using heavy equipment to knock down parts of the toppled structure.
Questions have been raised about tin cans which were spotted being used as filler in some of the concrete pillar, although some construction experts have said that may not have caused any structural problems.
