LOS ANGELES (MarketWatch) — Authorities on Sunday arrested the fleeing owner of a Bangladesh building that collapsed earlier in the week, killing at least 364 people who were inside the structure and possibly hundreds more, reports said.

The news came shortly before reports of a fire breaking out while rescue crews tried to dig survivors out of the rubble. Reports said one of those who managed to stay alive for five days, a female garment worker, was killed when the blaze erupted.
