Reporter of an independent radio station Ekho Moskvy was stabbed in the throat in her office on Monday and currently she is battling for life at a hospital after surgery.
Deputy editor Tatyana Felgenhauer is best known for her popular morning radio show that she co-hosts.
Doctors are giving the best course of treatment to the 32-year-old and have put her in medically-induced coma.
The assailant said for about five years he had been in telepathic contact with the journalist.
The station said he came to the office with a purpose and entered by spraying gas in security guard’s face on the ground floor. He very well knew where to go and went straight to the 14th floor of the building.
Police said the attacker had personal grudge against the journalist as he claims she had been haunting him since 2012.
Moscow Mayor Sergei Sobyanin said he is shocked and monitoring the treatment of the popular Ekho Moskvy host.
Meanwhile, it is also known state-owned Russian media have long targeted the journalist for her critical reporting.
About two weeks ago Rossiya 24 said the radio station is an arm of the US State Department claiming to have been paid for destabilizing society ahead of the presidential election scheduled for next year in March.
Novaya Gazeta newspaper editor-in-chief Dmitry Muratov said the authorities have failed in responding to the recurrent attacks.
There has been a string of attacks on opposition activists and reporters in recent time in Russian capital.
