Story of woman seeing Mas Selamat

The msm reported that a woman saw Mas Selemat crossing Thomson Road and looking lost. And Mas Selamat was taking a stroll, unhurried and without fear of being discovered. How credible is this story?

If that was Mas Selamat, it means that he either sneaked out or walked out of the detention centre on his own, unassisted. And he had all the time in the world to walk all the way to Thomson Road
