Man's body found in Murray River

An NSW man has swum to shore with a suspected broken arm to raise the alarm after a fishing boat accident that left another man dead.

A search was launched for a missing man on Wednesday evening after the injured 54-year-old man told police that their four-metre tinnie had overturned on the Murray River.

The body of a 64-year-old Lavington man was found several hours later, while a dog that was in the boat was found safely on the river bank.
