I heard on the news the convicts were allowed to have duffle bags while in jail and the power tools could had been brought back to their cells that way. They needed power tools to open the man hole cover it was chained up . I think I hear that correctly on the news.

"Jun 8, 2015 - Two prisoners used power tools to escape from the maximum security prison in ... a steam pipe and finally they ended up in the street in a manhole cover.” ... The manhole cover is chained and padlocked from the inside" YUP I was right the manhole was chained and padlocked so they needed the power tools , they may had taken the tools to use to
break into houses etc.
