A person who spiked candy with tranquilliser and gave them to children at a youth camp in the area has pleaded guilty to sexual crimes against two boys both nine and ten years old.
The defendant was arrested after eight minors and one adult fell ill at the location in July.
The senior citizen, from the Nottinghamshire area, confessed to a series of 17 offences when he stood at Leicester Crown Court on the end of the week.
However, he denied one of the sexual offences he was facing, which was concerning a young boy.
Ruben was remanded in custody prior to a further hearing on November 28th.
'Candy game'
The legal representative, presenting evidence, described the defendant's actions to the judicial body.
She said his victims were under-privileged children who were attending a summer program which he managed.
The defendant conducted a "treat game" with the minors, the legal counsel said, in which he would access the children's bedrooms when they were settling down and ask them to eat sweets "as fast as possible".
She stated to the judge Ruben had conducted this practice with the young males "repeatedly", and children had earlier experienced illness the subsequent day.
She explained the man had been capable of justifying this repeatedly as the minors being "overwrought by enjoyment", until his stepson had concerns in recently.
The prosecutor continued: "Recently" his family member had suspicions about what was going on, with valid cause.
"They decided to examine in the defendant's belongings."
The prosecutor said materials including infant oil, ointment and medical needles were located, and his family member alerted the authorities about his worries.
She stated the man went on to conduct the "candy game" with six boys that night - July 26th - and they were all ill the subsequent day.
"Authorities" had not responded by that stage," she added.
The police watchdog, the Independent Office for Police Conduct, previously told that it was reviewing Leicestershire Police's handling of the events.
Mrs Prior explained the youngsters were struggling to walk due to their sickness, so the stepson contacted the police again.
She stated the defendant then conducted the "treat game" in a area of five children.
