A person who spiked treats with tranquilliser and gave them to children at a youth camp in the area has admitted sexual crimes against two boys who were nine and 10.
The accused was detained after eight minors and an older person experienced illness at the location in the summer month.
The elderly man, from the Nottinghamshire area, pleaded guilty to a series of 17 offences when he stood at the judicial center on recently.
Yet, he refused to admit one of the sexual offences he was facing, which was involving a young boy.
The accused was kept in jail prior to a further hearing on 28 November.
'Treat game'
The prosecutor, prosecuting, described the defendant's actions to the legal proceedings.
She said his victims were children from difficult backgrounds who were participating in a summer camp which he managed.
The defendant engaged in a "sweet game" with the youngsters, the legal counsel stated, in which he would access the sleeping quarters when they were settling down and request they to eat sweets "as quickly as they can".
She informed the proceedings the defendant had engaged in this activity with the boys "for many years", and minors had previously become sick the following morning.
She stated Ruben had been successful in rationalizing this repeatedly as the children being "overstimulated by activities", until his family member had concerns in recently.
The prosecutor added: "In the summer" his family member had suspicions about the situation, for good reason.
"They decided to examine in the man's possessions."
Mrs Prior KC said objects including baby oil, Vaseline and injection devices were located, and his stepson contacted the authorities about his concerns.
She explained the defendant proceeded to engage in the "treat game" with six children that evening - July 26th - and they were all ill the next day.
"Authorities" had not responded by that stage," she stated further.
The regulatory agency, the Independent Office for Police Conduct, had stated that it was examining the police response of the situation.
The prosecutor explained the youngsters were struggling to walk due to their sickness, so the stepson called the law enforcement a second time.
She said the defendant then played the "sweet game" in a area of five youngsters.
