An individual who laced sweets with tranquilliser and distributed them to children at a summer camp in the area has pleaded guilty to sexual offences against two children aged between nine and ten.
Jon Ruben was taken into custody after eight youngsters and one adult fell ill at Stathern Lodge in July.
The elderly man, from the Nottinghamshire area, admitted guilt to a multiple criminal counts when he appeared at Leicester Crown Court on Friday.
However, he denied one particular crime he was accused of, which was against a nine-year-old child.
The accused was held in detention prior to a additional proceeding on 28 November.
'Candy game'
The prosecutor, presenting evidence, outlined Ruben's offending to the legal proceedings.
She explained his victims were disadvantaged youngsters who were participating in a summer camp which he operated.
Ruben conducted a "candy game" with the youngsters, the prosecutor said, in which he would enter the boys' rooms when they were settling down and request they to ingest treats "as quickly as they can".
She informed the proceedings Ruben had played this game with the children "for many years", and youngsters had previously fallen ill the subsequent day.
She stated the man had been successful in rationalizing this over a long period as the youngsters being "overwrought by enjoyment", until his stepchild had worries in recently.
The legal representative stated further: "In the summer" his stepson had concerns about what was going on, justifiably.
"They decided to investigate in the man's possessions."
The prosecutor explained items including infant oil, petroleum jelly and syringes were discovered, and his stepson notified the law enforcement about his suspicions.
She stated the defendant went on to play the "sweet game" with six youngsters that night - Saturday 26 July - and they were all ill the subsequent day.
"Authorities" had not gone out by that point," she stated further.
The police watchdog, the police conduct office, previously told that it was reviewing Leicestershire Police's handling of the incident.
Mrs Prior stated the minors were having difficulty walking due to their sickness, so the family member called the authorities again.
She explained the man then conducted the "candy game" in a space of five children.
