POLICE on Tuesday released details and pictures of what escaped terrorist Mas Selamat Kastari could have been wearing when he escaped from the Whitley Road Detention Centre last Wednesday afternoon.

He might have been in an off-white round-neck T-shirt, brown trousers and a pair of black rubber slippers, which are the standard uniform for detainees at the detention centre where he had been held since 2006 under the Internal Security Act.

He also had a greenish grey baju kurong - a very loose blouse with just a small neckline, worn over a sarong usually wrapped around the lower part of the body - with him.

The terrorist made his escape when he was being taken from his individual cell to see his family members last Wednesday. While being led to the family visit room, he asked to go to the toilet and fled from there.

As the fugitive has been on the run for almost six days, police said he is likely to have discarded the prison attire and baju kurong.

Anyone who has seen the discarded clothes and slippers should call call the police immediately. Police believe Mas Selamat is still in the country and urged the public to help track him down.

So far, police have received more than 600 calls and 170 emails from members of the public, providing leads for the round-the-clock search by police, military and Special Operations Command forces.

Noting that some of the information was two or three days old, AC Wong said anyone with leads or tips-off should call the police immediately and not hold them back. He reiterated that no tip-off was too small for the police to chase up.

Asked if extra reserves will be brought in in the manhunt, AC Wong said the current search forces are not stretched yet.

On Tuesday morning, about 100 Gurkhas and security forces combed through the Bukit Timah nature reserves and the Dairy Farm area.

Police also carried out massive searches in the Choa Chu Kang and Woodlands areas overnight till the early hours on Tuesday, after a man was seen running away from enforcement officers.

The fruitless hunt was called off after about six hours. On-going search will focus on forested areas and unoccupied buildings. Police are also going from home to home in private residential estates on the fringe of forested areas, distributing leaflets of the wanted man.

In Kuala Lumpur, Malaysian police chief said on Tuesday that there is no evidence to indicate that Mas Selamat is in the country.

'There is no information about the suspect entering the country. We always cooperate with Singapore,' he was reported as saying at the Bukit Aman police headquarters.
