A reporter was present at Hollow Way Recreation Ground in Oxford earlier today while the site remained closed.
The recreation ground had been shut for most of the morning, with police tape positioned across every entrance and officers stationed at the location.
The circumstances that led to the closure had not been established at the time of the report, and no further information was available from the police.
The reporter was attempting to obtain clarification.
Thames Valley Police was approached for comment at around 7.30am, but the force had not provided a response.
Photographs taken at the scene showed the cordoned-off entrances and police presence around the recreation ground.
People living near the site have reacted with shock following the incident and its proximity to their homes.
Residents have expressed concern about the sudden closure and the police activity in the area.
