A Japanese snorkeling instructor has drowned on Rota in the Northern Marianas.
The Department of Public Safety says the Japanese man was snorkeling at the Pinatang Dive Site.
It says his name won't be released until the next of kin is notified.
A preliminary investigation shows he was on a snorkeling trip with three customers, along with a boat captain.
It was the second drowning incident in the CNMI this year.
