Tutkimme eilistä uhkausta laittomana uhkauksena. Tämän hetkisten tietojemme mukaan mikään ei viittaa siihen, että asukkaiden tai alueen muiden toimijoiden tulisi välttää joitakin paikkoja tai jättää jotain tekemättä uhkauksen vuoksi. #lupoliisi #espoo https://t.co/HY1yc1Bg8u

On the basis of current police information, "it is safe to do business as usual in the shopping center and other affiliates, such as the library".
However, the police says that "our patrols will be moving in the shopping centers of Espoo in the coming days" as a part of "everyday cooperation" with these kind of businesses.
The newspaper Helsingin Sanomat informed that Siim Rosenthal, the general manager of Iso Omena, confirmed to the news agency STT that the managers of the shopping center and the police have been "in close contact" and the security level at the mall has been raised "immediately".
The Emergency Response Center and police departments have received plenty of tips from the public about this issue yesterday and this morning.
