A 75-year-old man was arrested on Tuesday under the Protection of Children from Sexual Offences Act, two days after he allegedly assaulted a minor girl at Vizhinjam.
The man has been identified as Gopinathan, a resident of Nellikunnu.
According to the police, the incident took place at his shop when the nine-year-old child went to make a purchase.
She told her parents about the incident only on Tuesday, the police said.
