Several instances of people dressed as clowns were reported to have approached children at various primary schools.
Multiple reports were lodged, the police told on Monday, adding that they are “verifying the facts with an education centre on their alleged involvement in the incidents”.
Messages circulating on social media also alleged that the people dressed as clowns had offered money to children to follow them.
The Singapore Police Force reminded members of the public to stay away from strangers and to report any suspicious people or activities.
“Call 999 if you require immediate assistance from the police, or visit the nearest Neighbourhood Police Centre to speak to a police officer,” it said.
The police did not name any education centre.
Speaker of Parliament Tan Chuan-Jin took to Facebook on Monday, sharing a partial screenshot of a letter from a primary school notifying parents that the police have been alerted to “persons dressed as clowns seen loitering around primary schools and requesting them to follow them”.
He also posted a picture of a man dressed as a clown outside what appeared to be a school near Bedok South.
“Whoever is doing what I assume to be some viral marketing nonsense, stop it! People dressed as clowns have been seen loitering around primary schools asking students to follow them. Please remind your children, do not follow them and report to the police.
“I trust the police are investigating this. It’s not amusing and just plain dangerous,” Mr Tan wrote.
