A MAJOR investigation is underway after a man's body was found hog tied and dumped in a Sydney street, with a gun shot wound to his head. The horrific discovery was made late last night when a passerby noticed a sheet covering an object in the gutter of a Bankstown street. Upon lifting the sheet, the witness found the body of a man, face down with black cable ties binding his hands behind his back. The dead man was dressed in a blue t-shirt and grey track suit pants. He had black runners on his feet. It is understood he did have some form of identification on him, although it is unclear at this stage if police have located his family. Although Bankstown Hospital is only meters from where the body was found in Antwerp St, police do not believe he had been a recent patient. Detectives have spent the morning canvassing the area, desperate to find clues to explain the man's shocking death and how he came to end up in a gutter, covered by a sheet. Residents in the street said the first they knew of the horrific discovery was when the road was filled with police cars, just before midnight. "It's scary stuff," one neighbour said. Students arriving at a local high school were this morning ushered away from the crime scene, only meters from their building.
