Glasgow Airport is fully operational again after emergency services were called to an incident there last night.
Police were called to reports of a spillage in an aircraft hold area at about 8.25pm.
Five fire engines and a number of specialist resources were also sent to the scene.
Police said the spillage was deemed safe and there are no suspicious circumstances.
The check-in hall was cordoned off while tests were carried out but was later re-opened.
A Glasgow Airport spokesman said: "Scottish Fire and Rescue representatives were called to the airport in response to concerns raised over a substance found on a piece of inbound luggage.
"Tests were conducted to determine the content of the substance and the main check-in hall was cordoned off, as is standard procedure.
"The incident has now been stood down and the airport is fully operational."
