I read there.... "that the Security stopped them from evacuating saying the fire was taken care off"...

Did anybody catch him? question him? Why he said so?

Even if he did make a mistake why did he not help the nursery kids and staff in escaping? or why he didnt help the Fire brigade to locate the nursery?...

Something looks funny...
Was he a security? or was he a "fake security" trying to stop the kids from leaving?
