My name's Ed Butler and for assignment on the documentary from the BBC World Service this week.

Many have bars on the windows.
There are some of just dozens of such complexes in this part of Southeast Asia that are thought to be home to thousands,

She's a 35-year-old professional from Sri Lanka.

scary and ill-explained journey, found herself gazing at a massive walled compound.
