CRIME Library has joined the search for Singapore's most wanted man.

On Saturday night, volunteers from the group that helps search for missing people went to 51 SMRT train stations and six bus interchanges to put up a total of 57 posters of fugitive Mas Selamat Kastari.

The posters had Crime Library's trademark 'Missing' heading. Explaining this, the group's founder, Mr Joseph Tan, said 'Escaped' and 'Wanted' sounded too much like the police's posters.

At least three other groups also distributed over 8,000 posters of the fugitive provided by the Ministry of Home Affairs across the island on Saturday.

One group of eight teenagers split up to distribute 5,000 posters across Singapore, including Toa Payoh, Bedok and Jurong.

Leader of the group Nurul Asyikeen Azhar, 19, said: 'I want to do my part and reach out to the public.'

Mr Leonard Ong, 27, a project executive, led a three-man group in handing out over 1,000 posters in the city area last night.

Madam Cynthia Phua, an MP for Aljunied GRC, led her group of over 40 grassroots leaders and others. They gave out 2,000 posters around Kovan MRT station.

The reaction from those approached was mixed. Some took the leaflets eagerly while others declined, saying they already knew all about Mas Selamat.

Taxi driver Quek Siow Soon, 58, allowed the posters to be put up behind the front seats in his taxi.

'As a citizen, it's my duty to help,' he said.

But housewife Ngern Mui Tiang, 64, declined to accept a leaflet, saying she is illiterate.
