Police say they dispersed a gathering of more than 50 people having a party in Bryn, Port Talbot.
A picture posted on Twitter by South Wales Police shows a gathering taking place on what appears to be a tennis court.
There are tables and chairs, along with a number of gazebos to protect the people taking part from the weather.
The tweet from @SWPNeathPTalbot said: "Gathering of 50+ with sound system and alcohol dispersed in Bryn tonight by the Op Bergamot team. We’re not out of the woods yet people - stay home if you can!"
While pubs have re-opened outdoors, people are still required to maintain social distancing.
Not everyone was supportive of the police action.
One person commenting on the post said: "I agree ...........BUT how is this any different to 50+ people gathering in a pub garden (which is allowed)."
But another tweeted: "I see it everyday, people having house parties, street parties, mixing with other households. I’m so scared we are going to have a second spike."
