A person who spiked candy with sedative and distributed them to youngsters at a summer camp in the area has confessed to sexual offenses against two boys who were nine and 10.
Jon Ruben was taken into custody after eight children and one adult experienced illness at Stathern Lodge in mid-summer.
The elderly man, from the Nottinghamshire area, pleaded guilty to a total of 17 charges when he appeared at the courthouse on Friday.
However, he refused to admit one particular crime he was facing, which was concerning a nine-year-old child.
Ruben was kept in jail before a additional proceeding on late November.
'Sweet game'
Mary Prior KC, prosecuting, outlined the defendant's actions to the judicial body.
She stated his those affected were children from difficult backgrounds who were participating in a summer program which he managed.
The man engaged in a "treat game" with the children, the legal counsel said, in which he would enter the children's bedrooms when they were preparing to sleep and tell them to eat sweets "as fast as possible".
She told the court the defendant had played this game with the children "over an extended period", and children had earlier experienced illness the next day.
She stated the defendant had been capable of justifying this over a long period as the minors being "overstimulated by activities", until his stepchild had concerns in recently.
The prosecutor continued: "This year his stepson had worries about the situation, for good reason.
"They decided to examine in the man's possessions."
Mrs Prior KC explained items including baby oil, petroleum jelly and medical needles were discovered, and his stepson contacted the police about his concerns.
She said the man went on to conduct the "sweet game" with six children that time - July 26th - and they were everyone unwell the next day.
"Law enforcement" had not responded by that stage," she continued.
The regulatory agency, the Independent Office for Police Conduct, previously told that it was investigating Leicestershire Police's handling of the events.
Mrs Prior stated the youngsters were unable to walk properly due to their condition, so the family member notified the police once more.
She stated the defendant then conducted the "sweet game" in a area of five minors.
