MOSCOW (AP) — A Russian radio station says the man who stabbed and seriously wounded one of its journalists has been diagnosed with schizophrenia.

Ekho Moskvy host and deputy editor-in-chief Tatyana Felgenhauer was stabbed in the neck at the station's Moscow office on Oct. 23. The attacker, Boris Grits, has been in custody since then awaiting trial.

Ekho Moskvy reported Wednesday that doctors at Moscow's Serbsky hospital diagnosed Grits, a dual citizen of Russia and Israel, as suffering from paranoid schizophrenia.

Felgenhauer said on the air that she trusts the doctors' conclusion and expects authorities to keep Grits in isolation. She has undergone rehabilitation for her injuries.

Ekho Moskvy has been critical of Russian authorities and its programs often make figures in political and business circles angry. Some of its journalists have received threats.
