Joss Goodchild, who had been on a walk along the nearby canal, described seeing four police cars blocking Byewaters as officers “questioned local workers”, while someone he believed was a male received treatment.
He added that he saw an air ambulance leaving just before 2pm.
The force confirmed armed police, the dog unit, and a police helicopter were deployed.
While enquiries continue police asked anyone with information to call 101, or report it online, quoting ISR 327 of 6 June.
