Interpol has identified a suspected paedophile as 32 year-old Christopher Paul Neil from Canada.
The man worked as an English teacher in South Korea and was last at Bangkok's international airport on 11 October.
Neil allegedly posted digital images of himself sexually abusing 12 boys. The images had been digitally altered to hide his identity, but experts in Germany created an application that reversed the masking effects.
Interpol posted the images online, leading to 350 tip-offs from the public. Interpol was able to track down Neil's passport number, birth date, name and work history.
The international law enforcement agency is asking the public to report any information on Neil's current whereabouts.
