Joggers find man dead in Brisbane park

Police are trying to determine how a man died after his body was found by joggers in a Brisbane park.

The 48-year-old Norman Park man was found lying in a drain near a bikeway in a park at Stones Corner, in the city's south, just before 6am on Thursday.

He had a gash to his head.

The man was moved from the drain in an attempt to resuscitate him but was pronounced dead at the scene.
