This is the shocking moment a drone was spotted delivering methamphetamine to inmates at a prison in Indonesia.

Footage shows the aerial device flying over an inmate housing block before dropping a package into the Class IIA Narcotics Prison in Bandung, West Java, on Sunday.

The drone then zipped away as prison security guards rushed inside the facility to intercept the parcel. They seized two packets of meth weighing 25 grammes and detained the suspected recipient, Alvi Muhammad, 29, who claimed he had ordered the contraband for 18 million IDR (1,100 USD) through social media.

Ahmad Tohari, head of the prison, said officials will strengthen surveillance and security systems to prevent a repeat of the incident.

He said: 'This is a new challenge for the correctional system. Technology should be for rehabilitation, not smuggling.'

Authorities said they are investigating how Alvi gained internet access inside the penitentiary, where inmates are banned from using mobile phones.

They said he will be charged under Articles 114 and 112 of Law Number 35 of 2009 concerning narcotics.

Senior Commissioner Aldi Subartono, Bandung Police Chief, said: 'This is not just an attempt at smuggling, but has entered the phase of utilising technology to avoid surveillance. We are still investigating who controlled the drone and where he operated the device from.'

Police said they were analysing the drone's flight path and model to trace its origin.

Indonesia has some of the strictest drug laws in the world, with harsh penalties including life imprisonment andthe death penalty for trafficking or possessing large quantities of narcotics.

However, the illegal drug trade has continued to thrive in the country due to weak border security, limited personnel and resources, and corruption.
