A total of 19 people, including 15 identified as Turkish security officials, were indicted Tuesday in Washington in connection with scuffles that broke out outside the Turkish ambassador’s residence here in May during a visit by the Turkish president, authorities said.

All were charged by a D.C. Superior Court grand jury with conspiracy to commit a crime of violence, said the U.S. Attorney’s Office for the District of Columbia

According to the indictment, the goals of the alleged conspiracy were to assault and kick protesters gathered in Sheridan Circle and to assault police who tried to stop the attacks.

Many of those indicted were also charged with assault that involved kicking.

The office said two of those indicted have been arrested, but the others are at large.

The alleged attacks were directed toward about 10 to 20 people in the circle who were protesting on May 16 against Turkish President Recep Tayyip Erdogan.

The office said two of those indicted have been arrested, but the others are at large.

It was not clear Monday where the others are, or whether diplomatic immunity could hamper efforts to prosecute them.
