MERCED (CBS / AP) — Members of a Central Valley drug task force say they’ve seized millions of dollars worth of methamphetamine in what is believed to be the largest meth bust ever conducted in the valley.

Merced County District Attorney Larry Morse said as part of an investigation that began with the purchase of one pound of methamphetamine in April, agents with the Merced Multi-Agency Narcotics Task Force later seized 330 pounds of the drug.
