South Korean police chief admits "heavy responsibility" for Halloween stampede disaster

South Korea's police commissioner general was among a number of officials who apologized for the deadly Halloween stampede that left at least 156 people dead and 151 more injured over the weekend. Yoon Hee-keun said on Tuesday that the police response to the disaster was "inadequate."

"I feel a heavy responsibility, as the head of one of the related government offices," Yoon said in a televised news conference.

Yoon said the National Police Agency was looking into how officers on the ground handled the crowd surge, and into the fact that emergency services received a number of calls alerting them to the seriousness of the crush as the situation deteriorated. Yoon said the police response to those calls was "insufficient."
