A Maryland gang member is accused of running a scheme to smuggle contraband into prison by "corrupting" 13 female prison guards from behind bars, four of whom he impregnated.

A federal indictment says Tavon White has been charged in the plot to smuggle drugs, cell phones and other contraband into the Baltimore jail and other corrections facilities, along with the prison guards, six of his fellow inmates and five others with gang ties who allegedly operated outside the jails.

The indictment also says the ring involved sex between the inmates and guards, which led to four of the officers becoming pregnant by White, the leader of a jailhouse gang called the Black Guerrilla Family.

White is accused of "corrupting" the female officers through personal and sexual relationships and other bribes and convincing them to join his ring, Fox Baltimore reports.

MyFoxDC.com reports the ring became increasingly brazen and confident over time, with White quoted as saying: "You understand me? This is my jail. I am dead serious, I make every final call in this jail."

White was being held at the Baltimore City Detention Center awaiting trial on a charge of attempted murder at the time.

The gang members and the corrections officers have been charged with conspiracy, drug possession and distribution and money laundering.
