U2 concert cancelled after gun scare

The Globe Arena in Stockholm was evacuated at around 8pm on the 19th September over a security threat. It is reported that a gunman gained access to the arena after he claimed to be an off-duty police officer. When Arena security realised their error, a full evacuation was ordered. The concert has been reportedly re-scheduled for Tuesday evening.
