Detective Superintendent Joe Marston said: “We are in the early stages of the investigation to establish the circumstances of what has taken place.
“I would appeal to anyone who was in the vicinity of the park and surrounding homes in the area who had seen or heard anything to come forward and speak to us.
“I also urge people in the area to check your CCTV and dashcam footage to see if it has captured any footage, no matter how small, as any information may help with the investigation.”
