August 29, 2007 (RFE/RL) -- The lawyer for one of the three Chechen brothers arrested in connection with the 2006 killing of a prominent Russian journalist says his defendant is innocent, and that the crime is "far from being solved."

Russian Prosecutor-General Yury Chaika announced on August 27 that 10 people had been arrested in connection with the slaying of Anna Politkovskaya, an investigative journalist and fierce Kremlin critic who was murdered in Moscow in October 2006.

Chaika also suggested that those ultimately responsible for the crime were people based abroad who sought to discredit President Vladimir Putin and destabilize Russia.

Attorney Murad Musayev represents one of the three Moscow-based Chechen brothers arrested -- Tamerlan, Djabrail, and Ibragim Makhmudov. The attorney told RFE/RL's North Caucasus Service on August 28 that Chaika's announcement was little more than scare-mongering.

"The entire speech of the prosecutor-general resembled a certain collage of populist cliches -- sort of an essay that combined all the demons of Russia. Individuals from Chechnya, corrupt law-enforcement people, someone vicious and scary who is sitting abroad and contemplating a revolution in Russia, and so on," Musayev said.

Musayev was quoted this week on the kavkaz-uzel.ru website as saying that there is no evidence linking his client -- whom he has not identified specifically -- with the killing, and that his client did not even know who Politkovskaya was before his arrest.

The daily "Kommersant" on August 28 quoted Musayev as claiming his client had been repeatedly physically abused during questioning, including being hit in the head with a bottle.

Musayev also said the investigation has reportedly concluded that the three Chechens had no personal grievance against Politkovskaya, but simply agreed to kill her for "a large sum of money."

Following the Russian prosecutor-general's announcement, the United States urged the Russian authorities to push forward with the investigation.

State Department spokesman Tom Casey said any acts that appear aimed at intimidating journalists or limiting free expression should be of particular concern to any society.
