BEIJING, Jan. 29 (Xinhuanet) -- Police have arrested four people in connection with a nightclub fire that killed 231 people in southern Brazil.

Two are club owners and the other two are members of the band that was performing. But no charges have been filed against the men. They will be held initially for five days while authorities investigate Sunday’s blaze in the Kiss nightclub in Santa Maria.

Meanwhile, funeral services have been held for several of the 21 victims, most of them college students 18 to 21 years old. Some of the victims were minors. Most died from smoke inhalation rather than burns.

Initial reports suggest the tragedy was the result of a serious of failures, including no fire alarm, no sprinklers, fire escapes and faulty extinguishers.
