Kyrgyz security services have seized a contacts database belonging to murdered Uzbek journalist Alisher Saipov.
The 26-year-old was shot dead by an unidentified gunman as he walked out of his office in the city of Osh, near the border with Uzbekistan, on Wednesday.
Saipov was one of the most outspoken journalists in Central Asia and was well-known for his harsh criticism of Uzbekistan's President, Islam Karimov.
A Kyrgyz official has said Uzbek agents may have been involved in the murder.
Ombudsman Tursunbay Bakir Uulu said that according to reports received by Kyrgyz security officials, a "special service" of the neighbouring republic had been ordered to kill the journalist.
Here is the Reporters without Borders report on Uzbekistan for 2006.
The organization calls Uzbekistan's President Islam Karimov a predator of press freedom.
The Committee to Protect Journalists called on Kyrgyzstan's President Kurmanbek Bakiyev to fully investigate Saipov's slaying.
