Seven people were arrested Wednesday following a month-long investigation into a methamphetamine manufacturing operation in Plymouth, Massachusetts.

Plymouth Police executed a search warrant around 3 p.m. at 55 Spooner St. following what they described as a lengthy investigation into the manufacture and sales of methamphetamine at that location. The U.S. Drug Enforcement Administration and Massachusetts State Police also participated in the bust.

During the search of the home, police said they found a sophisticated meth lab, along with many items and materials used in the manufacture of the drug. Also located was a quantity of methamphetamine, illegally possessed pharmaceuticals and psilocybin mushrooms.

The lab and all materials used to manufacture the drug were safely collected and dismantled by DEA agents.

Those arrested included:

  • Richard Pearson, 41, of Plymouth, for the manufacture and possession of methamphetamine and conspiracy to violate the controlled substance act. He was held on $200,000 bail.
  • David Hill, 20, of Marshfield, for the manufacture and possession of methamphetamine and conspiracy to violate the controlled substance act. He was held on $10,000 bail.
