An airport near Stockholm was evacuated Sunday after potential traces of an explosive powder were detected on a passenger’s bag.

Further testing revealed no explosive traces, according to police, and Skavsta Airport was reopened, Reuters reported.

Swedish airport officials had closed the departure lounge at Skavsta and halted outgoing flights.

Parts of the check-in area and baggage hall of the depature terminal were evacuated, airport spokesman Joakim Lindholm said.

At least three flights were delayed more than two hours while the bomb squad checked the suspect bag.

Arrivals were not affected, Lindholm said.

“The bag belong to an elderly Swedish lady, who was traveling to Poland,” police spokeswoman Anette Wilhelmsson said, according to the Wall Street Journal.

She was being questioned by officers.
