A person who spiked treats with tranquilliser and gave them to youngsters at a youth camp in the region has admitted sexual offenses against two boys aged between nine and ten.
The defendant was taken into custody after eight minors and a grown-up experienced illness at the location in July.
The 76-year-old, from the Nottinghamshire area, pleaded guilty to a multiple criminal counts when he stood at the judicial center on Friday.
Nevertheless, he refused to admit one of the sexual offences he was charged with, which was concerning a young boy.
The defendant was held in detention before a additional proceeding on late November.
'Sweet game'
The legal representative, handling the case, detailed Ruben's offending to the judicial body.
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 prosecutor stated, in which he would enter the sleeping quarters when they were getting ready for bed and request they to ingest treats "as quickly as they can".
She stated to the judge the man had engaged in this activity with the children "for many years", and minors had previously become sick the subsequent day.
She stated Ruben had been able to explain this for many years as the minors being "overexcited from fun", until his stepchild had worries in recently.
The prosecutor added: "Recently" his stepson had worries about the situation, for good reason.
"They decided to investigate in the man's possessions."
The prosecutor stated items including baby oil, petroleum jelly and syringes were located, and his stepchild contacted the police about his suspicions.
She said Ruben went on to engage in the "sweet game" with six boys that night - Saturday 26 July - and they were all ill the following morning.
"The police had not responded by that stage," she stated further.
The oversight body, the police conduct office, previously told that it was investigating the police response of the events.
Mrs Prior stated the youngsters were struggling to walk due to their sickness, so the stepson called the authorities once more.
She stated the defendant then engaged in the "sweet game" in a area of five minors.
