NZ mine probe hears of warnings
Harry Bell told the official inquiry into last year's disaster that he had called for the mine to be shut down.

Mr Bell, whose nephew was killed in the explosion, was called as an expert witness and was not working in any official capacity in late 2008, when he said he raised concerns.
Pete Rodger, 40, from Perthshire, and Malcolm Campbell, 25, from St Andrews, Fife, were among the victims.
