The 78-year-old man pleaded guilty to five of the 79 counts against him when arraigned before the Central Criminal Court jury on Tuesday.

He had pleaded guilty before the start of the trial to assault causing harm to the complainant on the same date.

The teen faces two counts of attempted rape and one for sexual assault of the same female on a date last year when he was aged 16.

Sentencing the man on Monday, Mr Justice Kerida Naidoo said there was a breach of trust and degradation in the offending, involving young children.
