The developer of a high-rise building that collapsed during the Taiwan earthquake on Saturday has been arrested. Liu Shih-Chung was held on suspicion of negligent homicide after 17-story Weiguan Jinlong (Golden Dragon) residential complex in Taiwan's oldest city of Tainan collapsed during the 6.4-magnitude earthquake, claiming the lives of at least 39 people, as HNGN previously reported.

Rescue efforts are still under way and rescue teams are making use of heavy equipment in order to save more than 100 people that are still believed to be buried under the debris.

The Taiwanese ordered an investigation into the collapse after pictures surfaced showing cooking oil cans inside the exposed wall cavities, which raised questions about the building's construction and the materials used to build the structure, according to CNN. The building is in an area where sturdier construction is required.

Local media outlets also reported the mixture of polystyrene with concrete inside the structure's supporting beams, according to Reuters.

The building, constructed in 1994, is one of 11 structures that collapsed on Saturday, but the only high-rise tower in the city to have been reduced to rubble in the quake.
