Mr Wong's two videos
The first video uploaded on YouTube on Sunday shows Mr Joel Wong dressed as a clown and scaring people in various parts of Singapore. It opens with the line: "Since its (sic) nearing Halloween, I decided to dress up as a clown and scare some Singaporeans."
Police officers, who responded to a call for assistance at Block 489C, Tampines Street 45, at 10.40pm on Saturday, spoke to Mr Wong.
Another video, which features behind-the-scenes footage, revealed that the pranks took place over three days last week.
Police investigations are ongoing.
