A man who contaminated candy with sedative and provided them to youngsters at a summer program in the area has confessed to sexual offences against two boys who were nine and ten years old.
The defendant was detained after eight youngsters and a grown-up experienced illness at the location in mid-summer.
The elderly man, from Ruddington in Nottinghamshire, confessed to a multiple criminal counts when he was present at the courthouse on the end of the week.
Nevertheless, he refused to admit one of the sexual offences he was facing, which was against a nine-year-old child.

'Treat game'
Mary Prior KC, presenting evidence, outlined the defendant's actions to the judicial body.
She said his targets were children from difficult backgrounds who were attending a summer program which he operated.
Ruben conducted a "treat game" with the children, the prosecutor said, in which he would go into the children's bedrooms when they were preparing to sleep 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 minors had earlier experienced illness the following morning.
She said the man had been successful in rationalizing this repeatedly as the minors being "overexcited from fun", until his stepchild had suspicions in recently.
The prosecutor added: "In the summer" his family member had worries about the situation, with valid cause.
"They resolved" to examine in the individual's items."
The prosecutor said objects including baby oil, Vaseline and injection devices were located, and his family member notified the authorities about his suspicions.
She said the man went on to engage in the "treat game" with six youngsters that evening - Saturday 26 July - and they were everyone unwell the subsequent day.
"Authorities" had not arrived by that time," she continued.
The oversight body, the investigative body, had stated that it was reviewing law enforcement's management of the incident.
Mrs Prior stated the minors were unable to walk properly due to being ill, so the stepson notified the authorities once more.
She stated the defendant then engaged in the "sweet game" in a space of five youngsters.
