A police force has warned parents of fines after a group of 20 youngsters were caught playing football.
Derbyshire Police responded to reports of a large group of youngsters at the Etwall Leisure Centre on Monday at roughly 1.05pm.
The Etwall, Hatton and Hilton Safer Neighbourhood Policing Team (SNT) said they were "horrified" to find the group had forcibly made their way onto the locked pitches.
The force said the youths made a "hasty" getaway after spotting police.
The incident prompted police to issue a warning to parents, saying: "Do you know where your kids are? Do you know what they are getting up to?"
Police said they know the names of some of the youngsters involved and they will be "dealt with accordingly".
"If a child breaches the rules then as their guardian, YOU will be held responsible for paying the fine.
"This may seem harsh but we need to ensure these rules are being followed so that one day in the not too distant future, we can be lift the restrictions and start getting back to a state of normality."
The statement continued: "A gathering of 20 is simply not acceptable and quite frankly irresponsible in the times we are all living through.
"Officers were also disgusted by the onslaught of rubbish that was just discarded about the place."
In accordance with lockdown easing measures, the government has stated outdoor sports can begin again from March 29.
Grass roots football, golf as well as other facilities like tennis and basketball courts are scheduled to reopen.
Indoor sports are likely to resume on May 17- the same time the rule of six takes effect for indoor gatherings.
Gyms are planned to reopen on April 12- with swimming pools likely to open in the second stage of lockdown easing, just after Easter.
Boris Johnson has raised hopes of a ‘normal’ summer by announcing plans to lift all Covid restrictions in England by June 21.
Mr Johnson told MPs: “A wretched year will give way to a Spring and a Summer that will be incomparably better”.
He later added that the “crocus of hope is poking through the frost”.
But in a dramatic shift in tone, he stressed that his approach must now be “cautious” to avoid a fourth national lockdown.
And he admitted that he could not guarantee that the measures would be “irreversible” - although he wanted them to be.
