Gunshots and a police helicopter were heard by residents in the Arbourthorne area, who were sent into a state of worry on Wednesday night.
Posts from residents emerged on social media around 11pm on May 5 asking why there was a helicopter flying above the area.
Later on a large police presence was seen on Beldon Road, including three police cars, a dog unit, and a drone.
Residents then claimed on Facebook and Reddit that they had heard six gunshots earlier that night.
Residents in the Norfolk Park cottages and the Park Grange area confirmed they had heard what sounded like gunshots that night, and that the police helicopter had been flying in the area for over an hour.
South Yorkshire Police have been contacted but have so far declined to comment.
Stay tuned for updates as they come.
