A jobless man who told police that accused terrorist Mas Selamat committed suicide was jailed for 12 weeks, news reports said on Friday, dpa reported.
Govindaraju Narayanasamy, 66, was drunk when he called police on March 30 from a public phone at a coffee shop.
"I think Mas Selamat has already committed suicide, and he could be around this area," The Straits Times quoted Govindaraju as telling the officer on the line. He identified himself as "Cobra."
Mas Selamat Kastari, 41, is at large after escaping from a detention centre February 27, triggering a nationwide manhunt and checks by Malaysian and Indonesian officials.
He was accused of being the head of the Singapore branch of Jemaah Islamiah, the South-East Asian Islamic terrorism network with links to Osama bin Laden's al-Qaeda organization.
He allegedly planned to hijack a plane and crash it into Changi Airport.
The intoxicated man said he wanted to meet with police. When an officer showed up, Govindaraju said, "Mas Selamat will come and bomb Block 19" of an apartment complex.
He was arrested. A voice test showed he was the prank caller. A Singapore court sent him to jail on Thursday.
In a separate case, Siew Kow claimed he had captured the fugitive. The 56-year-old man, also jobless, was accused of calling police 18 times over an 11-hour period on April 9.
