A tourist left behind on a dive trip swam all night, covering nearly 10 kilometers through shark-infested water before reaching land in Taveuni, Fiji Monday.

Thomas Holz, 40, of Berlin, Germany, was out a scuba diving trip with three other tourists at Rainbow Reef, near Viani Bay in Vanua Levu, according to the local Fiji Times newspaper.

He surfaced after running out of oxygen and waited for the dive master to return with the other divers. A local police spokesman said that when the dive master resurfaced with the other tourists, they couldn't find Holz. They searched until nightfall, and began again early at 5 a.m. Monday, according to the Fiji Times.

"The currents were strong, and my main fear was for my family in Germany. Even though I was tired, I hung on to the oxygen cylinder and kept swimming," Holz told the Fiji Times. "Then early this morning [Tuesday], I felt the seabed and just screamed out for help before I collapsed on the shore."

A local woman heard his cries and helped him from shore. Holz has recovered and is continuing his tourist activities on an eco tour.
