Emergency services and the PSNI dog and helicopter crew have been working in Ballymena today after someone was heard crying out for help.
A member of the public reported hearing the person call out about 7am today in the grounds of the ECOS Centre before daylight.
A PSNI spokesperson said: "Was this you? This morning just before 7am police attended the grounds of the ECOS Centre in Ballymena after a member of the public reported hearing a cry for help.
"This has resulted in a search operation involving Northern Ireland Fire and Rescue Service, the police helicopter and PSNI dog unit.
"Nothing has been found.
"There is a possibility that this was perfectly innocent as the path was flooded at the time.
"If you were in this area, maybe out for a run and can help us get to the bottom of it then please let us know by phoning 101 reference number 216 dated 28th December 2020."
