The bust happened just before 4 p.m. Wednesday at a home on Webster near Fresno in Central Fresno.
Officers served a search warrant at the home where they believed residents were selling drugs to Bulldog gang members and others.
Investigators say they found an ounce of meth and a stolen handgun in the home.
Eight people were arrested, including three alleged gang members.
Two children were also taken from the home, and an officer spotted them during the bust when one of the suspects put them over a fence.
