The man, whose identity was not disclosed, was travelling in Thailand at the time of the catastrophe.
“The man was reported as disappeared even before the tsunami, and his family feared that he may have died in the tsunami. But Thai authorities have now confirmed that he is alive,” police spokeswoman Linda Widmark told AFP.
The man has not contacted his family or authorities himself, but he renewed his travel visa and Thai authorities were therefore able to confirm his identity and well-being, she said.
A total of 448 Swedes have been confirmed dead after the December 26 tsunami, spawned by a massive earthquake off Indonesia, struck countries around the Indian Ocean, killing an estimated 217,000 people.
The total number of Swedes killed or missing has dropped by one to 543 now that the man in Thailand has been located.
