An individual who contaminated treats with tranquilliser and distributed them to children at a summer program in the area has confessed to sexual offenses against two young males aged nine and ten years old.
The defendant was taken into custody after eight minors and a grown-up fell ill at the facility in July.
The 76-year-old, from the Nottinghamshire area, confessed to a multiple criminal counts when he appeared at the judicial center on Friday.
Yet, he denied one of the sexual offences he was facing, which was involving a nine-year-old child.
The defendant was held in detention ahead of a further hearing on November 28th.
'Treat game'
Mary Prior KC, prosecuting, described the criminal behavior to the court.
She explained his those affected were disadvantaged youngsters who were attending a summer program which he managed.
The defendant conducted a "sweet game" with the children, the legal counsel said, in which he would enter the sleeping quarters when they were preparing to sleep and request they to consume candy "as fast as possible".
She informed the proceedings Ruben had conducted this practice with the boys "repeatedly", and youngsters had previously become sick the subsequent day.
She stated Ruben had been successful in rationalizing this over a long period as the minors being "overwrought by enjoyment", until his family member had concerns in recently.
The prosecutor stated further: "In the summer" his family member had suspicions about the situation, with valid cause.
"They resolved" to examine in the individual's items."
Mrs Prior KC said items including baby oil, Vaseline and medical needles were located, and his stepson alerted the police about his suspicions.
She stated the man continued to play the "candy game" with six children that evening - Saturday 26 July - and they were all sick the following morning.
"Law enforcement" had not gone out by that time," she added.
The regulatory agency, the police conduct office, earlier informed that it was examining the police response of the situation.
The prosecutor said the children were unable to walk properly due to their condition, so the stepson notified the authorities again.
She said the defendant then conducted the "candy game" in a space of five minors.
