An individual who laced treats with tranquilliser and distributed them to children at a youth camp in the region has pleaded guilty to sexual offences against two young males both nine and 10.
Jon Ruben was arrested after eight children and a grown-up became sick at the facility in mid-summer.
The 76-year-old, from the Nottinghamshire area, admitted guilt to a multiple criminal counts when he stood at Leicester Crown Court on Friday.
However, he refused to admit one particular crime he was facing, which was concerning a young boy.
Ruben was remanded in custody prior to a additional proceeding on 28 November.
'Candy game'
Mary Prior KC, handling the case, outlined the defendant's actions to the court.
She explained his those affected were children from difficult backgrounds who were staying at a summer camp which he ran.
The defendant played a "candy game" with the children, the legal counsel stated, in which he would go into the children's bedrooms when they were preparing to sleep and tell them to consume candy "as fast as possible".
She informed the proceedings Ruben had engaged in this activity with the children "over an extended period", and minors had previously become sick the subsequent day.
She stated Ruben had been successful in rationalizing this for many years as the youngsters being "overstimulated by activities", until his stepchild had worries in recently.
Mrs Prior KC added: "Recently" his stepson had concerns about what was going on, for good reason.
"They chose" to have a look in the man's possessions."
The legal counsel stated items including infant oil, petroleum jelly and injection devices were located, and his family member notified the police about his suspicions.
She said the defendant went on to play the "sweet game" with six boys that night - July 26th - and they were all ill the subsequent day.
"Law enforcement" had not gone out by that time," she stated further.
The regulatory agency, the police conduct office, had stated that it was reviewing the police response of the events.
Mrs Prior explained the youngsters were having difficulty walking due to being ill, so the stepson contacted the police once more.
She stated the man then played the "candy game" in a area of five minors.
