Looking at the cut lock, the plate thickness would be in the region of 3/4" MS plate. Now, that would take a nozzle not less size 5/32" to cut with ease. I think the thugs were smart enough to know that, one set of oxy-acetylene would not have accomplished the job and therefore, they came with a spare oxygen cylinder ( It takes two to three cylinders of oxygen to exhaust one cylinder of acetylene). Now, when that jinga police commander says the implements were left behind, one can only laugh. What he sees down there must have been the first oxy cylinder.Poor man!!

......btw, why would Equity be having strong room doors made of MS in this day and age??. That is sooo stupid!!
Nothing great was ever achieved without enthusiasm.
