A police chief who led the investigation into Stephen Shield’s activities says she is happy with the result.
Detective chief inspector Jo Edwards, of Lancashire Police, said: “I am pleased that Mr Shield has been convicted of these offences.
“The victim in this case had lived with the knowledge of Mr Shield’s offending for a long period of time; this has had a significant impact upon him.
“It was a difficult decision for the victim to come forward and I am pleased that he felt confident enough in the constabulary to help bring this man to justice.
“The fact that these convictions come a long time after they were committed shows that we will always take any allegations of sexual abuse extremely seriously and will investigate them thoroughly no matter how long ago they happened.
“I would encourage people with any information about sexual abuse or who has been a victim of sexual abuse to come forward and report their concerns confident in the knowledge it will be investigated appropriately.”
Shield will be sentenced on December 13.
