Emergency services have responded to an aviation incident in regional South Australia.
The first round of police and paramedics were called to Perponda, 111km east of Adelaide, about 5pm (ACST) on Thursday.
Speciality MedSTAR paramedics were then called to the site, in the Murray Mallee region, shortly after 5.30pm.
Initial reports had indicated a light aircraft had run into trouble.
However, emergency services were unable to locate any incident.
'An emergency alert was activated. However, nothing was located and there was no emergency,' an SA Police spokesperson later told Daily Mail.
It appears the triggering of the alert could have been a mechanical malfunction or human error.
