Four D.C. police officers were indicted Wednesday in connection with an assault outside a Northwest Washington nightclub last June in which a District Heights man was beaten so severely he lost an eye, according to officials and the man’s lawyer.

The officers, who were off-duty at the time of the June 10, 2011 fight, were involved in the incident outside the Lotus nightclub in the 1400 block of K Street, police officials said in a statement released late Wednesday night.

During the brawl, two club patrons were embroiled in a fight with several individuals, some thought to be bouncers at the club, police said. One of the patrons, Walter Blair II, 24, of District Heights, was taken to a hospital for treatment but lost his right eye as a result of the fight, his attorney, Ronald Karp, said last year.

A total of nine people were indicted after more than a year-long investigation by the D.C. police department’s internal affairs division, officials said.

Police did not release specific information about the charges. No police officials could be reached for comment at the department’s public information office late Wednesday.

Detectives recovered security-video footage of the fight and confirmed the identities of three officers, all of the 1st District. They were identified as Kenneth McRavin, Thaddeus Modlin and Nikeith Goins, police said.

The fourth officer who was indicted is Yolonda Lampkin, also of the 1st District, officials said.

It was unclear what role the officers allegedly played in the incident.
