A man, who sexually abused three boys and a woman, has been jailed for 19 years.
Dennis Butler targeted victims over four decades, abusing three boys under the age of 14, as well as a woman.
West Midlands Police is praising those he abused for finding the 'courage to come forward'.
Detectives are highlighting the case as an example of the support offered to anyone who comes forward to report sex abuse – no matter how long ago it happened.
The crimes came to light when one of the victims confided in a friend, and was then spoken to by police at his school in March last year.
Butler, 61, was arrested the next day and then released on bail while the investigation continued.
Two more victims then came forward to give detailed accounts of sexual abuse over a number of years.
One told police:
Butler, of Chantry Road, Handsworth, faced 21 charges including rape, indecent assault, and sexual assault.
He was found guilty of all charges on 17 November following a two-week trial at Birmingham Crown Court
On Friday, he was jailed for 19 years, and ordered to spend a further five years on licence.
