Mas Selamat Kastari was arrested in Malaysia's southern Johor state
A top terrorism suspect has been arrested in Malaysia more than a year after his escape from a prison in Singapore, authorities say.
Officials said Mas Selamat Kastari had been detained in a joint operation between Malaysia and Singapore in Malaysia's southern Johor state.
He is the suspected Singapore leader of Jemaah Islamiah, blamed for attacks including the 2002 Bali bombings.
His escape through a toilet window triggered a worldwide manhunt.
Mas Selamat Kastari is also alleged to have plotted to crash a hijacked plane into Singapore's international airport.
Walter Chia, a spokesman for the Singapore's embassy in Kuala Lumpur, said authorities were interrogating the suspect.
Singapore's Straits Times said he had been detained on 1 April.
Indonesian authorities arrested Mas Selamat Kastari on immigration violation charges in 2003.
He was handed over to Singapore in 2006, where he was detained under the city-state's Internal Security Act - a law which permits indefinite imprisonment without trial.
But he escaped in February 2008, managing to squeeze through the toilet window at his detention centre and climb over a fence while guards waited outside the bathroom.
Jemaah Islamiah, which has links to al-Qaeda, is blamed for the bombings on the Indonesian island of Bali in 2002 which left 200 people dead.
