Public park not public?

This is just stupid.

IT was a 15-minute nap on a park bench. And it cost him $200 - equivalent to a comfortable night's stay in a three-star hotel complete with a soft bed and fluffy pillows.

An NParks spokesman told The New Paper that Mr Kassim was fined as he 'was found sleeping in the park shelter with his colleague, and had repeatedly ignored our ranger's actions to wake him up'.

Five days after he was issued the ticket, Mr Kassim received a letter from NParks detailing his offence and asking him to pay the $200 fine.

How can NParks impose this fine when there is no express prohibition against sleeping in a park? Next, they will be penalising citizens who gather to listen to speeches in public about censorship or failed investments.

EDIT: Finally, someone is trying to make some sense of this.
