A person who spiked treats with tranquilliser and gave them to children at a youth camp in the region has confessed to sexual offenses against two children aged between nine and ten.
The accused was taken into custody after eight youngsters and one adult experienced illness at Stathern Lodge in mid-summer.
The 76-year-old, from Ruddington in Nottinghamshire, confessed to a total of 17 charges when he was present at the judicial center on Friday.
However, he refused to admit one of the sexual offences he was facing, which was against a nine-year-old boy.
The accused was kept in jail before a further hearing on November 28th.
'Sweet game'
The legal representative, presenting evidence, outlined the defendant's actions to the legal proceedings.
She said his victims were under-privileged children who were attending a summer camp which he ran.
The man played a "sweet game" with the minors, the prosecutor stated, in which he would go into the children's bedrooms when they were settling down and tell them to ingest treats "rapidly".
She stated to the judge Ruben had played this game with the young males "repeatedly", and youngsters had earlier experienced illness the subsequent day.
She explained the defendant had been able to explain this over a long period as the youngsters being "overexcited from fun", until his stepson had worries in recently.
The legal representative continued: "This year his stepchild had worries about the situation, with valid cause.
"They decided to have a look in the defendant's belongings."
The prosecutor stated materials including lubricant, petroleum jelly and injection devices were found, and his stepchild notified the authorities about his worries.
She said Ruben went on to conduct the "treat game" with six boys that night - Saturday 26 July - and they were everyone unwell the following morning.
"Law enforcement" had not responded by that point," she added.
The regulatory agency, the police conduct office, had stated that it was reviewing law enforcement's management of the events.
The prosecutor explained the minors were unable to walk properly due to their sickness, so the stepson contacted the police a second time.
She explained Ruben then engaged in the "candy game" in a space of five children.
