A Swedish prosecutor says that a computer specialist suspected of spying for Russia has been released from custody.

Prosecutor Mats Ljungqvist says the evidence against Kristian Dmitrievski "is such that the suspect cannot complicate the investigation."

Ljungqvist said Friday he cannot comment further because the case is "sensitive."

Dmitrievski, 45, was arrested Feb. 26 by Sweden's domestic security agency SAPO as he met with a Russian intelligence officer working at Russia's Embassy in Stockholm under diplomatic cover. SAPO said the Russian officer had recruited Dmitrievski and that criminal activity had been going on at least since 2017.

Dmitrievski has not been charged.

The Associated Press has identified the diplomat as Yevgeny Umerenko, who has left Sweden, according to the Swedish Foreign Ministry. The reason for his departure was not known.
