A man was arrested at Changi Airport in Singapore last week for buying a boarding pass — with no intention to board the plane.

The 27-year-old had purchased a boarding pass just so he could enter the transit area — a "protected place" — to say goodbye to his wife, the Singapore Police Force said.

"Investigations revealed that the man had entered the transit area to send off his wife," authorities wrote in a Facebook post. "He had no intention to depart Singapore."

The man was arrested on Aug. 25 for "misusing his boarding pass." In total, 33 people have been arrested this year for similar infractions, police said.

The transit area of the Changi Airport falls under the category of "protected places" — areas where "special measures are needed to control the movement and conduct of persons for public safety and security reasons."

Other protected places in Singapore include Singapore military bases, security headquarters and water treatment plants, according to the police force's website.
