A paedophile who admitted indecently assaulting a 17 month old baby has been given an indeterminate prison sentence.
Andrew Lintern, of Five Acres in Kings Langley, was arrested when he believed he was meeting a 13 year old girl intending to have sex with her.
The "child" whom he had been grooming for months online went under the name Jessie and was in fact a covert police officer.
At Southwark Crown Court in London on Monday (March 16) the former Oxford University research chemist was jailed for a minimum of three-and-a-half years. After this time he can be considered for parole.
He had previously pleaded guilty to indecently assaulting a 17 month old baby seven years ago, making, distributing and possessing 20,000 indecent images of children and travelling to meet a 13 year old girl after grooming her via the internet.
