'Treat game'
The legal representative, prosecuting, detailed the criminal behavior to the legal proceedings.
She explained his victims were children from difficult backgrounds who were staying at a summer camp which he managed.
The defendant conducted a "candy game" with the minors, the prosecutor said, in which he would go into the boys' rooms when they were preparing to sleep and tell them to ingest treats "rapidly".
She told the court Ruben had conducted this practice with the boys "for many years", and minors had previously fallen ill the subsequent day.
She stated Ruben had been successful in rationalizing this for many years as the youngsters being "overwrought by enjoyment", until his family member had concerns in recently.
Mrs Prior KC continued: "This year his family member had worries about what was going on, for good reason.
"They chose" to investigate in the defendant's belongings."
The legal counsel said objects including lubricant, petroleum jelly and medical needles were found, and his family member contacted the authorities about his concerns.
She explained the man continued to play the "sweet game" with six boys that night - Saturday 26 July - and they were everyone unwell the next day.
"Authorities" had not gone out by that point," she added.
The regulatory agency, the police conduct office, earlier informed that it was examining Leicestershire Police's handling of the incident.
The prosecutor explained the youngsters were struggling to walk due to their condition, so the stepson contacted the law enforcement once more.
She stated the defendant then played the "treat game" in a area of five youngsters.
