[From The Malaysian Insider]Sources told The Straits Times that the 48-year-old was tracked down based on intelligence provided by Singapore's Internal Security Department (ISD), and a joint operation by Malaysia and Singapore's security agencies eventually led to his arrest.
The capture of Mas Selamat brings to an end one of the largest manhunts ever undertaken by Singapore and its neighbours for a terrorist on the run.
A source said that the Singapore side had picked up a lead on Mas Selamat's trail towards the end of last year and pursued it.
When that proved to be a credible lead, they passed on the information to the Malaysian authorities.
So the lead is from Singapore, the $1million still stays in Singapore.
