Before this case, authorities in the area had announced several investigations related to espionage and acts of sabotage. In Romania, DIICOT and SRI described a fire at an industrial hall near the Carfil military factory as having been deliberately caused by a sabotage network coordinated from Russia, following the pretrial detention in Poland of a Ukrainian citizen suspected of having contributed to preparing the attack.
At the same time, two Belarusian citizens suspected of being part of the same cell were arrested in Germany, while in another case DIICOT announced the detention of a Russian citizen for photographing and transmitting information concerning Romanian and allied military sites, in anticipation of acts of diversion or hybrid-type sabotage.
