A person who spiked candy with sedative and distributed them to children at a youth camp in the area has confessed to sexual offences against two boys both between nine and ten.
The defendant was taken into custody after eight children and a grown-up fell ill at the facility in July.
The senior citizen, from the Nottinghamshire area, confessed to a series of 17 offences when he stood at the courthouse on recently.
Nevertheless, he refused to admit one of the sexual offences he was accused of, which was against a nine-year-old boy.
The accused was kept in jail prior to a subsequent court date on 28 November.
'Treat game'
The legal representative, presenting evidence, described the defendant's actions to the court.
She explained his those affected were disadvantaged youngsters who were staying at a summer program which he managed.
The defendant conducted a "candy game" with the children, Mrs Prior said, in which he would go into the sleeping quarters when they were settling down and tell them to ingest treats "as fast as possible".
She stated to the judge Ruben had conducted this practice with the boys "for many years", and minors had previously fallen ill the subsequent day.
She said the defendant had been successful in rationalizing this for many years as the youngsters being "overstimulated by activities", until his stepson had worries in recently.
The prosecutor stated further: "This year his stepchild had suspicions about what was going on, with valid cause.
"They resolved" to investigate in the individual's items."
The legal counsel explained materials including baby oil, petroleum jelly and medical needles were located, and his stepson alerted the police about his worries.
She said Ruben continued to play the "treat game" with six children that evening - July 26th - and they were everyone unwell the next day.
"Law enforcement" had not arrived by that time," she stated further.
The regulatory agency, the Independent Office for Police Conduct, earlier informed that it was reviewing law enforcement's management of the incident.
The prosecutor explained the children were having difficulty walking due to their condition, so the family member called the police again.
She explained Ruben then conducted the "treat game" in a room of five youngsters.
