A U.S. Park Police officer was taken to George Washington University Hospital on Thursday after a violent clash between police and a man at the Occupy D.C. camp in McPherson Square.

Based on preliminary information, Sgt. Dave Schlosser, a Park Police spokesman, said that police were called to the park shortly after 1 p.m. after reports of an intoxicated male assaulting a female.

Upon arriving, Schlosser said, police found several “extremely intoxicated individuals.”

Police arrested one man, who was not identified, for disorderly conduct. But the man resisted, police said, and he now also faces charges of assaulting a police officer.

About the same time, police attempted to arrest another man for disorderly conduct. The suspect became “extremely disorderly” and began fighting with officers, Schlosser said.

During the fracas, the man allegedly kicked an officer in the groin, requiring him to seek medical treatment.

A Washington Post reporter witnessed eight Park Police officers struggling to restrain the man on 15th Street near the intersection with K Street.

At one point, officers used a stun gun to try to restrain the man, authorities said. Several Occupy DC demonstrators became angry, resulting in some heated exchanges between them and the officers.

After struggling with the man for more than 10 minutes on the street, while curious lunchtime passersby watched, police hoisted him into the back of a police cruiser.

On the way to the station, the suspect kicked out the back window of the police car, Schlosser said.

The suspect, who has not been identified, has been charged with assaulting a police officer, disorderly conduct and destruction of government property.

The condition of the officer who was sent to the hospital was not known last night.

Despite concerns from some business leaders about the public safety and sanitation in McPherson Square, Park Service officials have maintained that past court decisions affirm protesters’ rights to maintain a “24-hour vigil” in the park.
