Portsmouth police are investigating after a man fell to his death hours before dawn Saturday.
Police say officers were called to the scene outside a parking garage near Hanover Street on an assault report.
Officers determined that two groups of men inside the Gaslight Night Club got into a dispute that continued outside.
The victim reportedly got separated from his group and sought refuge inside the garage where he tried to escape his pursuers by climbing over a railing, then fell to the sidewalk below.
He died at the hospital sometime later.
