Earlier in the day, a source in the city's emergency services told Sputnik that an unidentified explosive device had gone off on Friday under a Toyota Land Cruiser in northern Moscow, injuring the owner. A criminal case has been opened in connection with the incident, the source added.
"Don't worry. He is alive and fine. He will continue his work. No matter how hard they tried [to kill him], they failed," the assistant said, when asked about the circumstances of the incident.
The assistant confirmed that Prozorov was admitted to a medical facility and was receiving treatment.
"He has been injured, but fortunately not severely, so he is now conscious and able to communicate," the assistant said, adding that Prozorov was waiting for investigators to be questioned in connection with the incident.
In 2018, Prozorov moved to Russia and has since participated in investigating crimes believed to have been committed by the Ukrainian government. He has recently been working on a documentary about the events of May 2, 2014, in Odessa.
