The incident was initially reported by Bild as a gas attack, with the paper saying an unknown assailant had sprayed passengers with a mystery substance.
However, it now appears that information was incorrect.
Airport authorities say the exact cause of the incident is still unclear, but investigations are ongoing.
The check-in area was closed for a short time after the scare, before being reopened around 12.30pm.
Nobody was seriously injured during the incident.
