Valery Tsarenko told the outlet RusNews that law enforcement officers waited for his son to step out to a store before detaining him. The following day, Federal Security Service (FSB) officers arrived at the family's home with witnesses, conducted a search and seized a computer. Morozov was brought home for the duration of the search and then taken away again.
Tsarenko noticed scratches on his son's face and swollen hands. He suggested the swelling was caused by handcuffs in which Morozov was held all night.
Relatives and lawyers do not know where the activist is now. The reports do not specify the article under which he is being pursued.
According to Tsarenko, during the search security officers said Morozov was accused of ties to an unnamed "banned organization." The father said his son is not personally acquainted with the people the FSB officers mentioned.
Tsarenko later recorded a video address describing how FSB officers brought his son home for the search and then took him away again to an unknown location.
Morozov is a democratic socialist, a member of the student antifascist front and the socialist association Uchastiye, and a public environmental inspector. He has organized rallies in Izhevsk.
Morozov had earlier filed an application to hold a rally "against falsifications and for fair elections." The Izhevsk administration refused to approve the rally, citing the emergency condition of the "Forever with Russia" monument. Morozov and like-minded supporters then sued the mayor's office and appealed to the presidential administration.
A court ordered the Izhevsk administration to provide another location and time for the rally. On his Telegram channel, Morozov published a checklist for appealing a refusal to approve a rally.
