A student at the Department of Agriculture Graduate School said yesterday that he was beaten and held at gunpoint outside the school Monday night by three federal government security guards.

Charles A. Hawkins, 27, of 2705 13th St. NE, was treated at the Veterans Administration Hospital for bruises he said he suffered when he was arrested by the officers of the Federal Protective Service.

Hawkins was charged with simple assault.

Lt. McKinley Tyler of the Federal Protective Service said the incident occurred about 9 p.m., while Howkins and about 50 other students were waiting in line to sign out of the Department of Agriculture's south building at 14th Street and Independence Avenue NW.

"According to my officers, Mr. Hawkins was agitating them and creating confusion," said Tyler.

Tyler said the arresting officer, George Short, ordered Hawkins to leave the building. But when three officers attempted physically to remove him, Tyler said Hawkins announced that he was a martial arts expert.

That is when Short drew his service revolver and held Hawkins at gunpoint, Tyler said.

Hawkins is studying English and photography and is employed by the city to clean streets and alleys. He said he complained to guards because the sign-out procedure was so slow.

After signing out, Hawkins said, he continued his complaint. He said he ignored one officer's order that he leave the building. When two other guards were called, Hawkins told a reporter that he assumed a martial arts stance.

He said one officer jammed a night stick against his throat, another held him at gunpoint, and the third handcuffed him.

Tyler said FPS officers are authorized to draw their revolvers "whenever the life of someone else or the officer's life is in danger."
