The search exposed no links to Daesh," Andrae said during the press conference organized by the N-24 broadcaster on Saturday, Sputnik News reported.
"There is no indication that in addition to the criminal who committed suicide, there were others involved in the events on Friday. From our point of view, it is clear that we are dealing with a lone wolf," he added.
