Butler police swept up seven suspects — three of them siblings — during a Tuesday afternoon raid of a suspected drug apartment at 309 W. Cunningham St.

The operation, authorities said, took down a suspected methamphetamine lab at the home in front of the Salvation Army and a stone’s throw away from the district judge office and the Butler County Prison.

City officers, aided by Butler Township police and the state police clandestine lab team, seized potentially dangerous and hazardous materials used to cook methamphetamine.

Also confiscated was suspected meth, heroin, crack cocaine and marijuana, as well as other contraband including more than 100 syringes and a scale.

Police were already familiar with the apartment, where, they say, there have been “numerous overdoses” in the past several months.

The witness told officers that he had also seen occupants there making meth, according to court documents, using the “shake and bake” method.

The practice, also known as “one-pot” cooking, manufacture methamphetamine in one vessel, typically a 2-liter soda bottle or plastic Gatorade bottle.

The Butler County Assessment Office lists Gregory Bogacki of Butler Township as the owner of 309 W. Cunningham St.
