Korchagin remains on Interpol's lists, but since the Finnish side found no reasons for the extension of his detention, he is not going to be extradited to Russia.

The Central Criminal Police of Finland released Andrey Korchagin, the former chief of St. Petersburg’s Traffic Management Agency, who was detained last week, senior commissioner Tero Haapala told TASS.

"He was arrested last Thursday, and soon after all the circumstances were established, it was ascertained that we have no reason to hold him, so he has already been released," Haapala said.

He confirmed that Korchagin remains on Interpol's lists, but since the Finnish side found no reasons for the extension of his detention, he is not going to be extradited to Russia.

Haapala did not say whether Korchagin was going to stay in Finland. "He is now at large and therefore can go wherever he pleases," he said.

Earlier, the Russian embassy informed the TASS that Finland notified diplomats that Korchagin had been detained, while he did not turn to the embassy himself.

On Monday, the media reported that Korchagin was detained on Interpol's request on April 20 when he arrived at Helsinki. Before that, he had been wanted for several years and hiding abroad. Korchagin went off the radar in 2009, when the department he headed was searched in a fraud case.
