So, the people who discovered this crime - is it a crime? What would the offence be? - found that baked beans had been smeared all over the seats of swings, as well as the roundabout.
To be fair, it might not be illegal, but it's pretty mean. After all, this means that none of the children who might wish to use the park can get on any of the play equipment without getting covered in tomato sauce.
It seems as if the whole thing unfolded on Wednesday (16 September) at some point, and the alarm was raised by concerned parents in a local Facebook group.
They took a number of photos showing the damage that had been done, and told their fellow parents not to bother heading for the park, as it was completely out of use.
Nothing a decent hosing down or a convenient rainstorm couldn't sort out, admittedly.
The 'Spotted In Swanwick 2' group post said: "So today I take my little girl to Chapel Street Park, and this is what I found.
"Baked beans on the swings, the kids roundabout and on the basketball area. I don't understand.
"When we have all been cooped up for a while now, I would have thought people would want to look after parks."
The post later made it all the way as far as Twitter, where it has since been liked more than 20,000 times.
A lot of people seem to be pretty amused by the whole thing, rather than showing even a crumb of empathy for the children who can't use the play park because it has been covered in beans.
OK, it is actually pretty funny though, isn't it?
One person wrote: "I just can't bring myself to delete Facebook and it's because of posts like these."
A second observer commented: "I laughed through my nose and my nose alone."
Wait, what does that even mean?
A third said: "Back in my day we sat on the bean swing and we liked it.
"Entitled parents these days think their angels are too good for the bean."
Probably the pick of the bunch was the Facebook commenter who said: "To be honest in Heinzsight, I can see why they're upset."
