IndonesiaCai Changpan, 37, a Chinese death row inmate awaiting his sentence, escaped a prison on the outskirts of Jakarta by digging a tunnel through a sewage sewer.

Cai, who is awaiting the death penalty for smuggling in Indonesia, dug a hole from a prison cell in the Tangerang region that connects to a sewage pipe and from there onto an outside street on Thursday.

According to a fellow inmate, Cai planned to carry out the escape for 5-6 months, using tools stolen from a construction project in the prison's kitchen.

This Chinese prisoner was sentenced to death by an Indonesian court in 2017 for smuggling 135 kg of meth.

Cai also previously escaped from a Jakarta police detention center in 2017 by digging holes in the bathroom wall.

Indonesian police have put him on the list of most wanted criminals.
