FOR two years, Shashi Kumar Pubalasingam thought he had got away with raping a 69-year-old grandmother.
But he was eventually caught out by his own DNA sample in 2006, which he had given voluntarily to the police.
A task force was on the lookout for him after two other women were sexually assaulted in March that year.
The DNA of the perpetrator who attacked the two women matched that of the rapist of the grandmother, but the police did not know who he was.
They then looked through the records of 1,000 possible suspects and invited them to give samples.
Shashi, who was then 23 but had committed sexual offences as a juvenile, was one of them. He responded to the police's invitation to give his DNA, and they found a match.
