Felgenhauer, a popular morning news show host, is in a “moderately severe” condition following the attack, the Interfax news agency reported. She was placed in an induced coma after undergoing surgery and is expected to recover.
According to preliminary official accounts, the attacker, who is suspected of suffering from a psychiatric condition, had personal motives.
But colleagues close to Felgenhauer have blamed state media, pointing to a general atmosphere of hostility towards journalists who are critical of the Kremlin. Ekho Moskvy is among a handful of remaining Kremlin-critical media outlets in the country.
The case has been handed to a team of investigators tasked with investigating high profile incidents, the Investigative Committee said Tuesday in a statement.
