Nwaka convicted Adenekan on a count charge of defilement.
Adenekan committed the offence sometime in November 2016 at the school in Lagos.
He was arraigned on January 29, 2018, and had pleaded not guilty to a charge of defilement of a child.
According to the prosecution, the defendant defiled the two-year and 11-month-old girl by having sexual intercourse with her.
The offence contravenes Section 137 of the Criminal Law of Lagos State 2011 which recommends a life sentence for anyone convicted of defiling a child.
Nwaka in her ruling held that evidence before the court showed that the supervisor was guilty as charged.
“This defendant is conscienceless, wicked, an animal, and not fit to walk on the streets.
“I hereby sentence Adegboyega Adenekan to 60 years’ imprisonment. This is the sentence of the court,” the judge held.
“Schools should not cover up teachers who sexually abuse children.
“Parents should not be carried away by aesthetics of schools. This case may just be the tip of the iceberg as a lot of our children are suffering in silence.
“Parents should be bold enough to confront teachers and school management because a lot of our children are suffering in silence.
“I advise or recommend that the education and social welfare ministry workers should visit schools randomly to give them a check.”
