The elderly man, from that region, pleaded guilty to a multiple criminal counts when he stood at Leicester Crown Court on recently.

'Candy game'
Mary Prior KC, prosecuting, outlined Ruben's offending to the legal proceedings.
She explained his those affected were under-privileged children who were staying at a summer camp which he managed.
The defendant conducted a "treat game" with the youngsters, the prosecutor stated, in which he would access the children's bedrooms when they were settling down and tell them to ingest treats "as fast as possible".
She stated to the judge the defendant had conducted this practice with the boys "for many years", and youngsters had earlier experienced illness the subsequent day.
She said the defendant had been able to explain this repeatedly as the youngsters being "overstimulated by activities", until his stepchild had suspicions in recently.
Mrs Prior KC added: "Recently" his family member had suspicions about the activities, with valid cause.
"They resolved" to have a look in the man's possessions."
Mrs Prior KC explained materials including baby oil, Vaseline and medical needles were located, and his stepchild alerted the law enforcement about his concerns.
She explained Ruben went on to play the "treat game" with six boys that night - that Saturday - and they were all ill the subsequent day.
"Law enforcement" had not arrived by that stage," she stated further.
The regulatory agency, the Independent Office for Police Conduct, earlier informed that it was examining the police response of the events.
The prosecutor explained the youngsters were having difficulty walking due to their condition, so the stepson contacted the police once more.
She explained Ruben then played the "candy game" in a room of five children.
