A 21-year-old man has been jailed indefinitely after admitting he raped a girl aged four.
Liam Ineson, of Lancaster, subjected his victim to a six-month "campaign of abuse", police said, targeting her on a number of occasions earlier this year.
He was given an indeterminate sentence after pleading guilty to rape and sexual activity with a child.
Ineson, of Ryelands Road, will serve nearly six years before his sentence is reviewed.
Detective sergeant Simon Coates, of Lancaster police, said: "Ineson preyed on a young girl and then tried to make her keep the abuse a secret.
"He is a dangerous individual and the indeterminate sentence means he should not be released from prison until experts are satisfied that he no longer poses a threat to our community."
