An individual who spiked candy with tranquilliser and provided them to youngsters at a summer camp in Leicestershire has confessed to sexual crimes against two children aged between nine and ten.
The accused was detained after eight youngsters and an older person fell ill at the location in the summer month.
The 76-year-old, from the Nottinghamshire area, confessed to a multiple criminal counts when he was present at Leicester Crown Court on Friday.
However, he disputed one of the sexual offences he was accused of, which was concerning a nine-year-old boy.
Ruben was held in detention prior to a additional proceeding on 28 November.
'Sweet game'
The prosecutor, handling the case, detailed the defendant's actions to the legal proceedings.
She stated his victims were children from difficult backgrounds who were participating in a summer camp which he operated.
The man engaged in a "sweet game" with the minors, Mrs Prior stated, in which he would access the sleeping quarters when they were getting ready for bed and request they to eat sweets "as quickly as they can".
She informed the proceedings Ruben had played this game with the boys "for many years", and youngsters had earlier experienced illness the following morning.
She explained the man had been capable of justifying this repeatedly as the minors being "overexcited from fun", until his family member had concerns in recently.
The legal representative continued: "In the summer" his stepchild had suspicions about what was going on, with valid cause.
"They chose" to investigate in the defendant's belongings."
The prosecutor said materials including lubricant, petroleum jelly and syringes were discovered, and his family member contacted the authorities about his worries.
She said the defendant proceeded to conduct the "treat game" with six children that night - Saturday 26 July - and they were all ill the subsequent day.
"Authorities" had not responded by that time," she stated further.
The oversight body, the Independent Office for Police Conduct, earlier informed that it was examining law enforcement's management of the events.
The legal representative said the children were unable to walk properly due to their sickness, so Ruben's stepson notified the authorities again.
She explained Ruben then conducted the "sweet game" in a area of five children.
