#ON THE TV – In tomorrow's concluding two-part documentary 'Hostile Environment' (RTE 1, 21.35) actor Liam Cunningham explores the criminal world in the Seychelles. Also examined is the role of anti-piracy work, as almost one third of all the oil in the world passes through the Indian Ocean.

Cunningham highlights how the country is combating crime, and where Irish private security contractors have had an impact on turning around crime rates.

Former intelligence officers Declan Barber and Niall Scully were first brought to the island when the Seychelles government suspected sensitive information was being leaked.

This led to Barber and Scully recruiting former army ranger Seamus Griffin to set up and train the Tazar Unit, the Seychelles Anti-Terrorist Unit.

To date the unit has successfully stopped five pirate attempts, resulting in the release of 35 hostages and the capture of 63 pirates.
