Authorities have identified the additional body found in the Danube River as a South Korean man in his sixties, who had boarded the tourist boat that fatally sank two weeks ago.
The body was discovered some 110 kilometers south of the accident site near the town of Bolcske .
This brings the official death toll to 25, of them 23 South Korean tourists and two Hungarian crew members.
Only seven people are known to have survived and three remain unaccounted for.
Meanwhile, the search for the missing continues.
On Wednesday, a government rescue team from South Korea was expected to conduct search operations inside the boat, but they were stopped by Hungarian authorities due to unfinished legal procedures regarding the preservation of the boat.
The Korean team was later granted permission to search inside from Thursday morning, local time.
The Hungarian police began their search inside the vessel on Wednesday but they announced that they were not able to find any additional bodies inside the wreck.
In the meantime, the two sides are continuing their search along the Danube.
"The highest probability is that the bodies fell out of the ship during the crash, so if the bodies are not inside the ship then they must be in the water somewhere.
On the whole territory of the river the Hungarian police is doing a huge job, everyone is out on the water searching. The Minister of Interior yesterday doubled these forces and so the chance to find these bodies has grown."
Meanwhile, a Hungarian court has turned down a prosecutor's appeal against its decision to release on bail the Ukrainian captain of the cruise ship that slammed into the side of the tour boat, causing it to sink.
The captain, who has only been identified as 64-year-old Yuriy C, was arrested earlier this month, but the court decided to release him on bail of 53-thousand U.S. dollars.
The court ordered him to undergo police questioning twice a week and to wear an electronic tracking device so he cannot leave Budapest's city boundaries.
