(Baltimore Sun) Corrections officers at the Baltimore City Detention Center were preparing for a middle-of-the-night search of jail cells, aimed at rooting out drugs, cell phones, weapons and any other contraband inmates had stashed away. But the officers weren’t the only ones getting ready.

Hours before the planned checks in January, an FBI affidavit says, word reached Tavon White, an inmate who prosecutors say reigned as the jailhouse leader of a violent gang called the Black Guerrilla Family.

White’s alleged tipster, according to court records: a corrections officer at the jail.

The advance warning vividly illustrates the success with which federal authorities believe the BGF turned the downtown Baltimore detention center into a gang “stronghold.”Authorities around the country have struggled for years to dislodge gangs from jails and prisons. In Maryland for example, a 2009 investigation revealed widespread BGF activity at other corrections facilities.
