Singapore officials say two South Korean journalists arrested on suspicion of trespassing at the residence of the North Korean ambassador have been deported.

Singapore's Law and Home Affairs Minister K Shanmugam said Sunday that it was unwise to break into an ambassador's residence in any country in the world, and Singapore was no exception. He added that the case was closed.

The two men represented the Korean Broadcasting System News and were arrested on Friday. They were not accredited as media personnel in Singapore. The national broadcaster, more widely known as KBS, has apologized.

The maximum penalty for criminal trespass is a jail term of three months and a fine of 1,500 Singapore dollars. Another KBS journalist and an interpreter are also under investigation.
