A person who spiked sweets with sedative and distributed them to children at a youth camp in the region has confessed to sexual offences against two boys both nine and 10.
The defendant was arrested after eight children and a grown-up became sick at the facility in mid-summer.
The 76-year-old, from Ruddington in Nottinghamshire, pleaded guilty to a multiple criminal counts when he was present at the judicial center on recently.
Nevertheless, he denied one particular crime he was accused of, which was involving a nine-year-old boy.
The defendant was held in detention prior to a additional proceeding on November 28th.
'Candy game'
Mary Prior KC, handling the case, described the defendant's actions to the judicial body.
She stated his victims were children from difficult backgrounds who were attending a summer camp which he operated.
Ruben conducted a "candy game" with the children, the legal counsel stated, in which he would enter the children's bedrooms when they were preparing to sleep and request they to consume candy "rapidly".
She informed the proceedings Ruben had engaged in this activity with the young males "for many years", and minors had previously become sick the next day.
She explained Ruben had been able to explain this over a long period as the minors being "overexcited from fun", until his family member had suspicions in recently.
The prosecutor continued: "This year his stepson had concerns about the situation, for good reason.
"They resolved" to investigate in the defendant's belongings."
The prosecutor stated objects including lubricant, petroleum jelly and medical needles were located, and his stepson alerted the law enforcement about his suspicions.
She said Ruben went on to engage in the "candy game" with six boys that time - that Saturday - and they were all sick the following morning.
"The police had not responded by that stage," she continued.
The regulatory agency, the investigative body, had stated that it was investigating law enforcement's management of the events.
Mrs Prior said the youngsters were unable to walk properly due to being ill, so the family member notified the police once more.
She explained the defendant then engaged in the "treat game" in a space of five children.
