German authorities are investigating a suspected arson attack near the premises of major defense and security companies in Munich after two Bulgarian nationals were detained following the throwing of incendiary devices at a construction site.

The Bavarian State Criminal Police Office (LKA) said Friday that a 28-year-old woman and a 38-year-old man are due to appear before an investigating judge, who will decide whether arrest warrants should be issued. The two suspects were detained shortly after the incident at a nearby petrol station.

The incident occurred around midnight on Thursday in Munich’s Berg am Laim district, near facilities belonging to defense technology companies including Rohde & Schwarz and Helsing.

According to investigators, incendiary devices were thrown from a moving vehicle onto a construction site. One device ignited a fire that was quickly extinguished by police, while another device was rendered harmless by a bomb-disposal team. No injuries were reported and only minor damage was recorded.

Authorities have not established a motive and have not publicly confirmed which company, if any, was the intended target. The LKA said the investigation is continuing and that there are currently no indications of additional suspects.

The attack comes as German authorities are increasingly concerned about suspected acts of sabotage targeting critical infrastructure and defense-related facilities.

Bavarian authorities have indicated that a political motive is being examined, although investigators have not publicly attributed the Munich incident to any foreign government or organization. Reports have also raised the possibility that the attack could be connected to broader sabotage activity in Germany, but no such link has been established.

The Munich incident follows several other security cases in Germany that have heightened concerns about so-called hybrid threats. These include recent sabotage attempts involving power infrastructure and a failed drone attack at Leipzig/Halle Airport, which German authorities have attributed to Russia. Moscow has rejected those accusations.

Rohde & Schwarz develops communications, security and surveillance technologies used by government agencies and military customers, while Helsing specializes in defense technology, including military drones and artificial-intelligence systems.

The proximity of the suspected attack to both companies has prompted investigators to examine whether one of the firms was deliberately targeted. However, authorities have so far stopped short of identifying a specific target.

The two Bulgarian suspects have not publicly commented on the allegations, and their possible involvement remains subject to the ongoing investigation. Their appearance before the investigating judge will determine whether they remain in custody pending further proceedings.

German authorities are continuing to examine the circumstances surrounding the attack, including the suspects’ possible motives, connections and movements before and after the incident. (ILKHA)
