The Kunnamangalam police on Monday arrested a local Muslim Youth League (MYL) leader from Pullaloor on the charge of sexually abusing a boy.
Muhammed Rafi, the suspect who was charged under the Protection of Children from Sexual Offences Act, was remanded in judicial custody for 14 days.
The police said the incident took place nearly three months ago. The victim was a resident of an orphanage.
The police zeroed in on the suspect after tracking the registration details of a car which was used to allegedly abduct the boy.
The car had been sold out after the incident.
