1. On 27 February 2008, alleged terrorist Mas Selamat Kastari escaped from the Whitley Road Detention Centre, in Singapore.
The detention centre has armed guards, high wire fences and CCTV cameras. Singapore is a country where "security breaches are virtually unheard of",
Kastari is the suspected Singapore leader of the Southeast Asian 'terrorist network' Jemaah Islamiyah.
Jemaah Islamiyah has been blamed for bombings that killed 202 people, mostly foreign tourists, on Indonesia's Bali island in 2002. (Singapore detention center officials sacked over terror leader's ... / A PERFECT HIDING PLACE)
Singapore authorities have alleged that Kastari planned to crash seven bomb-filled trucks at various locations around Singapore.
In January 2006, Kastari was arrested by Indonesian anti-terror squads in Java and deported to Singapore.
He was suspected of plotting to bomb Singapore Changi Airport in 2002, and, according to the Singapore Police Force, he had initially planned to do so by crashing a plane into the airport.
However, Kastari has never been formally charged with any terrorism-related offences; instead, he was detained under the country's Internal Security Act, which allows indefinite detention without trial.
