The accused officer, who was only identified by her initials TM, received a wire transfer of about 14.5 million rupiah (US$1,040) from Dorfin’s parents before the escape, according to authorities.

She used some of the wired funds to buy items for Dorfin including a mobile phone with a SIM card, and also gave him a blanket which he may have used in the escape, said authorities.

“The money was transferred by the suspect’s parents,” West Nusa Tenggara senior police officer Agus Salim told reporters on Thursday.

Authorities initially said they believed Dorfin sawed through iron bars on a second-floor window and then rappelled to freedom with sarongs and blankets tied together. But they later said it was still unclear exactly how he made good on his escape.

Dorfin had also received packages from an unnamed woman in Bali, including one that contained a blanket, which is banned at the detention centre, Salim said.

“The second package wasn’t checked” by security, he added. “That was a fatal mistake – it might have contained a saw.”

The accused officer allegedly rebuffed concerns expressed by other police about Dorfin having a banned blanket.

A couple of security staff who were supposed to be working on the day of Dorfin’s escape also unexpectedly called in sick, Salim said, adding that their absence is being investigated.

Dorfin’s parents could not immediately be reached for comment.

Indonesia has some of the world’s strictest drug laws – including execution by firing squad for some traffickers.

The Southeast Asian nation is riddled with corruption at all levels of society and jailbreaks are also common. Inmates are often held in unsanitary conditions at overcrowded and poorly guarded prisons.

In 2017, four foreign inmates tunnelled their way out of Bali’s Kerobokan prison. A pair of the fugitives were captured a few days later, while two others – an Australian and Malaysian – are still on the run.
