A radio host was stabbed in the throat by an attacker Monday as she worked at Russia's "Echo of Moscow" radio station.
Tatiana Felgengauer was attacked at about 12:45 pm local time (5:45 a.m. ET) after the suspect broke into the studios, the station said.
The man was apprehended by security and handed over to police, it added.
Felgengauer's injuries were believed to be not life-threatening. However, the station said she had been hospitalized and was undergoing surgery.
The station’s chief editor, Alexei Venediktov, said the assailant blinded a security guard with a gas can before carrying out the attack, and that the episode was being treated as attempted murder.
The station posted photos of what it said was the weapon and of the suspect being hand-cuffed by police.
The motive for the attack was not immediately clear but a Russian interior ministry spokesman told reporters that a preliminary investigation suggested it was driven by "personal animosity," without elaborating. It was not known if Felgengauer knew the suspect.
Felgengauer had been on the air earlier Monday but was not broadcasting at the time of the attack.
“Echo of Moscow" is one of the few remaining Russian media outlets that provides a platform to Kremlin critics.
A regular contributor, journalist Yulia Latynina, fled Russia last month after saying a series of attacks had put her personal safety at risk.
