The car parks at a country park in Peterborough have been closed due to a "concerning" number of people failing to follow social distancing rules.
Nene Park Trust said they made the decision to close the Ferry Meadows car parks on Saturday until "further notice" for the safety of visitors and staff.
The Trust said staff were "very stretched" and unable to carry out their duties and the situation will be reviewed again on June 1.
