High-quality meth manufactured in two Greater Noida houses was stitched into garments and sent to ports in Mumbai and Kolkata, from where it was shipped abroad, police said on Wednesday, after two raids in the last fortnight unearthed an eye-popping amount of the substance - 75kg worth around Rs 350 crore - and a well-oiled narco operation that was both cooking and distributing it, reports Advitya Bahl.
