Investigators have released all of the people detained after last week's suicide bombing at a market in Vladikavkaz, a Russian newspaper said on Wednesday.
The September 9 attack targeted the main market in the capital of North Ossetia, part of Russia's troubled North Caucasus region. At least seventeen people were killed and over 190 injured.
The head of the Russian Federal Security Service (FSB), Alexander Bortnikov, said earlier that three people had been detained on suspicion of involvement in the blast. The paper said, citing the North Ossetian Interior Ministry and Investigative Committee, that more people had in fact been arrested, but that they had all now been freed.
Kommersant said the first suspect detained was a man who sold his car to the suicide bomber ahead of the terrorist attack. However, he was soon cleared of involvement in the bombing.
The identity of the suicide bomber has not yet been determined.
