PHOENIX — A West Valley drug laboratory that was making methamphetamine was busted Thursday, police said.

When police contacted an individual staying at a home in the 7300 block of W. Roma Ave., they smelled chemicals normally used in drug labs. Police immediately secured the home.

“It appears this lab was involved in what’s called ‘washing’ methamphetamine and that’s where you use different solvents, different chemicals to actually clean up methamphetamine so that it will have the appearance of what’s called ‘glass’ or ‘ice,'” said Phoenix Police Sgt. Tommy Thompson, adding that the treatment does not change the drug but gives it a cleaner look that is desired by dealers.

In all, Thompson said 20 gallons of liquid was seized from the home. The liquid likely contains methamphetamine that was undergoing the cleaning process.

An unnamed 26-year-old Hispanic male was arrested at the home.

It is unknown who owns the home

Thompson said the case is still on-going.
