At about 13:00 in Płock, police were alerted to suspicious items discovered during cleanup work in a theater’s basement, leading to the evacuation of 32 people and the deployment of specialized explosive‑detection teams.
Police Receive Alert
Around 13:00, officers received a report about suspicious objects uncovered during routine cleaning in a theater basement in Płock. Police and specialized mines and pyrotechnics units were dispatched to the site immediately.
Building Isolated and Evacuated
The theater was sealed off, and all occupants—32 workers and visitors present at the time—were safely removed. The premises were then fully isolated pending further inspection.
Explosive Confirmed
Specialists confirmed that one of the items was an explosive device. Other objects in the same room displayed combat‑grade characteristics and were secured for further analysis.
Investigation Aims to Trace Origin
Preliminary findings suggest the items may have been stored for at least several months, likely belonging to a former theater employee who died a few months ago. Investigators are examining how the materials entered the basement and whether they were prepared for use.
Operation Could Continue into Night
Police officers are methodically inspecting additional rooms, a process that may extend into the late hours. The theater remains closed until all checks are completed and evidence secured.
