His 14-year-old daughter said she was going to a birthday party with other girls her age.
Then Stomper Eric saw a photo of her and the other teens in a hotel room with at least seven guys. Bottles of alcohol were also spotted.
"During the night, alcohol was consumed and vaping occurred in the room," said Eric.
"As parents, we are deeply concerned and disappointed that such events were allowed at a Sentosa hotel, endangering the lives of our children and exposing them to substance and physical abuse."
In response to a Stomp query, the police confirmed a report was lodged and investigations are ongoing.
