An individual who spiked sweets with sedative and gave them to minors at a summer camp in the area has pleaded guilty to sexual offenses against two children who were nine and 10.
The accused was taken into custody after eight minors and an older person became sick at the location in the summer month.
The 76-year-old, from Ruddington in Nottinghamshire, pleaded guilty to a multiple criminal counts when he stood at Leicester Crown Court on Friday.
Nevertheless, he disputed a single sexual charge he was facing, which was against a nine-year-old boy.
The defendant was remanded in custody ahead of a subsequent court date on late November.
'Treat game'
The prosecutor, prosecuting, outlined the defendant's actions to the court.
She explained his victims were under-privileged children who were participating in a summer program which he ran.
The defendant conducted a "treat game" with the minors, Mrs Prior explained, in which he would enter the boys' rooms when they were preparing to sleep and tell them to ingest treats "as quickly as they can".
She informed the proceedings Ruben had conducted this practice with the children "over an extended period", and children had previously fallen ill the following morning.
She said Ruben had been capable of justifying this for many years as the children being "overexcited from fun", until his family member had worries in recently.
The legal representative added: "In the summer" his stepchild had worries about the activities, with valid cause.
"They decided to examine in the defendant's belongings."
Mrs Prior KC said materials including baby oil, petroleum jelly and injection devices were discovered, and his family member notified the authorities about his suspicions.
She stated the defendant proceeded to conduct the "treat game" with six youngsters that night - July 26th - and they were all sick the subsequent day.
"The police had not arrived by that point," she stated further.
The oversight body, the investigative body, had stated that it was examining law enforcement's management of the situation.
The prosecutor explained the minors were having difficulty walking due to being ill, so the family member contacted the police a second time.
She stated the man then conducted the "treat game" in a room of five youngsters.
