An unlicensed music event has been broken up and sound equipment seized, police said.
At about 00:30 BST on Monday, West Mercia Police officers attended Stafford Park in Telford, where about 100 people had gathered.
The "large gathering" had been advertised on social media, the force said.
Officers gave advice on social distancing laws and reported the organiser for summons.
Supt Jim Baker said: "When officers attended this unlicensed event it was clear that social distancing was not being adhered to and the gathering was posing a risk to the health of all those attending.
"Therefore it was quickly dispersed and the sound equipment seized.
"To the organisers of this sort of activity, I strongly advise that you seriously consider the risks you're creating for everyone in attendance and the wider community."
He added the public had been "instrumental" in reporting information that had led to illegal gatherings being dispersed.
