Four prison guards have been suspended after a Vietnamese woman on death row impregnated herself with a fellow inmate's semen to escape execution.
Nguyen Thi Hue, 42, paid a 27-year-old convict 50million Vietnamese Dong (£1,600) for his sperm, investigators said.
The male prisoner, Nguyen Tuan Hung, handed over his semen in syringes to Hue on two occasions in August 2015, the state-owned Thanh Nien newspaper reported.
The convicted drug trafficker then fell pregnant after artificially inseminating herself at the prison in the northern province of Quang Ninh.
Investigators and prosecutors have now confirmed that Hue is due to give birth in April.
