Australian Shaun Edward Davidson, 31, has taken part in an escape from Kerobokan jail.
Prison escapes are fairly common in Indonesia and authorities launched an investigation last month after around 350 inmates broke out of an overcrowded jail on Sumatra island in Riau Province.
The tower above the tunnel exit was not manned at the time due to a limited number of guards in the prison. "We just realized this morning [that] it's not working", Pasaribu said.
He was with Bulgarian Dimitar Nikolov Iliev, who was sentenced to seven years prison for money laundering in 2016, Indian Sayed Mohammed Said and Malaysian Tee Kok King, who were both serving jail terms over Indonesia's tough laws on drugs.
"We hope they haven't left Bali, so it is easier for us to catch them".
Staff noticed they were missing on Monday morning during a routine check.
