A person who spiked treats with tranquilliser and provided them to children at a youth camp in the area has pleaded guilty to sexual offenses against two boys both nine and ten years old.
Jon Ruben was detained after eight youngsters and one adult became sick at Stathern Lodge in July.
The 76-year-old, from the Nottinghamshire area, pleaded guilty to a series of 17 offences when he stood at the judicial center on Friday.
Yet, he disputed one particular crime he was facing, which was against a nine-year-old child.
The defendant was held in detention ahead of a further hearing on 28 November.
'Sweet game'
The prosecutor, prosecuting, detailed the criminal behavior to the court.
She said his victims were children from difficult backgrounds who were attending a youth camp which he managed.
The man engaged in a "sweet game" with the minors, the legal counsel stated, in which he would access the children's bedrooms when they were settling down and tell them to eat sweets "as fast as possible".
She stated to the judge the man had played this game with the children "repeatedly", 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 youngsters being "overexcited from fun", until his stepchild had suspicions in recently.
The prosecutor continued: "In the summer" his stepchild had suspicions about the activities, for good reason.
"They resolved" to examine in the man's possessions."
Mrs Prior KC explained items including lubricant, Vaseline and injection devices were located, and his family member alerted the authorities about his concerns.
She said the defendant continued to conduct the "candy game" with six children that time - Saturday 26 July - and they were all ill the following morning.
"Law enforcement" had not responded by that time," she stated further.
The oversight body, the police conduct office, earlier informed that it was examining the police response of the situation.
The prosecutor said the youngsters were unable to walk properly due to being ill, so the family member called the law enforcement a second time.
She said the defendant then played the "treat game" in a room of five children.
