An individual who spiked treats with sleeping medication and distributed them to minors at a summer camp in the region has admitted sexual offences against two children both nine and 10.
The accused was taken into custody after eight youngsters and an older person became sick at the location in the summer month.
The elderly man, from Ruddington in Nottinghamshire, pleaded guilty to a total of 17 charges when he was present at the judicial center on the end of the week.
Nevertheless, he refused to admit one particular crime he was charged with, which was against a young boy.
The defendant was kept in jail prior to a additional proceeding on 28 November.
'Candy game'
Mary Prior KC, presenting evidence, described the defendant's actions to the judicial body.
She said his those affected were children from difficult backgrounds who were participating in a summer camp which he operated.
Ruben conducted a "sweet game" with the children, the prosecutor explained, in which he would access the sleeping quarters when they were preparing to sleep and tell them to ingest treats "as quickly as they can".
She stated to the judge the man had played this game with the children "repeatedly", and minors had earlier experienced illness the next day.
She explained Ruben had been capable of justifying this over a long period as the children being "overwrought by enjoyment", until his family member had worries in recently.
Mrs Prior KC stated further: "Recently" his stepson had concerns about the situation, with valid cause.
"They decided to have a look in the man's possessions."
Mrs Prior KC stated objects including lubricant, Vaseline and injection devices were discovered, and his stepson notified the police about his worries.
She said the man went on to play the "sweet game" with six children that night - Saturday 26 July - and they were everyone unwell the next day.
"Authorities" had not responded by that stage," she continued.
The oversight body, the police conduct office, earlier informed that it was reviewing law enforcement's management of the events.
The prosecutor said the youngsters were struggling to walk due to their condition, so Ruben's stepson notified the police once more.
She stated Ruben then conducted the "sweet game" in a room of five minors.
