A teenager is being investigated for making a false police report after claiming he had been robbed of his wallet last month, said the police in a statement released on Thursday.

The 15-year-old made the report on April 18, claiming an unknown man had assaulted him along Toh Yi Drive before running away with his wallet containing $40 cash and some personal documents.

Subsequent police investigations established that the "victim" had made a false report after misplacing his wallet to avoid being reprimanded by his parents.

Investigations are ongoing. Anyone convicted of giving false information to a public servant may be jailed up to one year, fined up to $5,000 or both.
