A Marine Corps investigation of a melee at the Equus bar on Capitol Hill last month has concluded that the disturbance at the homosexual bar was "spontaneous" and "did not result from a deliberate, malicious plan."

A Marine spokesman said "an informal, voluntary contribution system" at the Marine Barracks on 8th St. SE has raised enough money to compensate the owners of the bar and several area residents who said their property was damaged during the late night incident Aug. 16.

A crowd of more than 100 persons, believed to include many Marines from the barracks, went on a brief rampage along 8th Street SE and Pennsylvania Avenue at 6th Street SE. At least five persons entered the bar at 639 Pennsylvania Ave. SE where customers were threatened and a window was broken.

A co-owner of the bar was struck and was treated for injuries at a hospital. The owners said damages are expected to total about $300.

The Marines said their investigation indicated at least five Marines took part in the disturbance, but that only one was identified. Officials said the Marines are cooperating with a continuing D.C. police investigation and inquiry by Mayor Barry's office into the incident.
