A tip to drug agents resulted in four arrests Wednesday after drug agents discovered methamphetamine, components of a meth lab and other drugs in a Buchan Road home near Pembroke. Bulloch County Drug Suppression Team Inv. Jim Riggs said an anonymous tip regarding possible drug activity led to a traffic stop, where Sabrina Boatwright O’Brien, 28, Buchans Road, and Wylie Edward O’Brien Jr., 29, of an A.O. Smith Road, Ellabell address, were found in possession of “a quantity of pseudoephedrine,” he said.
