MP David Hinchliffe has held top-level talks to find out how a child sex offender escaped from a bail hostel just yards from a nursery.
John McDermott, 45, had been staying at the hostel in Wakefield when he disappeared at 8am on Friday. He was supposed to be under strict supervision.
Mr Hinchliffe, the MP for Wakefield, whose constituency covers Kirkburton and Denby Dale, has spoken to representatives from the Home Office's Dangerous Offenders' Unit.
"Clearly I am concerned," he said. "When you have people released from prison into a non-custodial environment, there will be people who will occasionally disappear."
Police say McDermott is a dangerous sex offender, especially to young children. He had served prison sentences for sexually assaulting two young girls and a woman after he broke into their home. He had been living at the hostel under a licence, which has now been revoked.
Security surrounding sex offenders staying at the hostel was tightened in 2001. Then, William Knowles, who was serving four years for sexually assaulting a young boy, handed himself in after three days on the run.
McDermott may have been seen in London's Victoria coach station on Sunday morning.
He is white, 5ft 6in tall and weighs about 18 stone. He has a shaved head and wears glasses.
