DUSHANBE, May 4, 2016, Asia-Plus -- Russia''s Interior Ministry said an ethnic Tajik named Mahmadali Ahmadov, who is suspected of involvement in murder of a high-ranking police officer and five of his relatives, was detained at Moscow''s Domodedovo Airport on May 4 upon his arrival there from Dushanbe, Tajikistan.

Meanwhile, Russian media outlets report that Mahmadali Ahmadov was transported to Russia from Dushanbe.

“The fourth suspect -- an ethnic Tajik named Mahmadali Ahmadov -- was detained on May 3 while attempting to illegally cross the Tajik-Afghan border,” Sergey Solodovnikov, chief of the Russian Interior Ministry’s office for Samara oblast, was quoted as saying by Tass news agency.  “The suspect will be handed over to convoy in Moscow and then he will be transported to Syzran,” Solodovnikov said Wednesday afternoon.

We will recall that Jaloliddin Sadriddinov, a spokesman for the Interior Ministry of Tajikistan, told Radio Liberty’s Tajik Service that if Ahmadov was a Tajik citizen currently in Tajikistan, Dushanbe would not be able to extradite him to Russia because Tajik laws do not allow the extradition of the country''s own citizens.

The deputy chief of staff of the Russian Interior Ministry’s office for Samara oblast, Andrei Gosht, was found dead at his home in the Ivashevka settlement near Syzran on April 24 along with five of his relatives.

Russian federal investigators say three suspects arrested in connection with the murder of a high-ranking police officer and five of his relatives have confessed to the killings.

The investigators identified the three arrested men on May 3 as Roman Fataliyev, Islam Babayev, and Orxan Zahrabov, all natives of Azerbaijan.

On May 2, Russia''s Investigative Committee said the suspects were from Central Asia.

Russia''s Investigative Committee has said that all of the suspects will be charged with murder and robbery.
