"Passengers who enter the transit areas with a boarding pass should only be there for the purpose of travelling to their next destinations. Those who misuse their boarding pass to enter into the transit areas, with no intention to proceed to their next destinations, are liable for an offence under the Infrastructure Protection Act."
The offender may be prosecuted in court and fined up to $20,000 ($A21,400) or be jailed up to two years or both.
Police said it was the 33rd time this year a person had been arrested at Changi for misusing a boarding pass.
A woman from Macau faced court in March over an incident at Changi Airport in September when she allegedly entered the transit area to get a tax refund and didn't intend to leave Singapore, the Strait Times reported.
In January last year, a 20-year-old woman was arrested after she bought a ticket so she could meet members of a South Korean boy band at the airport. In another case that month, a 23-year-old woman who also didn't intend to leave Singapore used her boarding pass to go shopping at the airport.
Earlier this year two YouTubers made a video flaunting the fact that they illegally stayed at the airport for four days as part of an internet dare. They got away with it.
