Police were called to a church and ordered the worshippers to leave as they flouted the new lockdown rules in Wales.
The incident, which took place at New Hope Community Church in Cardiff, saw a team of South Wales Police officers storming into the premises to find the room was packed with people.
A woman attending the service at the church filmed the moment and shared the clip on social media.
She says in the video: "We are at church right now and the police just showed up.
"They have knocked on all the windows and the doors, they shined flashlights, so please pray for us right now.
"I'm just letting you know this is happening. This is in Cardiff. We are not even in a third world country right now, this is in Cardiff."
As she pans the camera across the room, the group is seen wearing face masks as they remain seated.
A policeman walks to the stage and informs the group that they have received phone calls from members of the public and explained that they are breaching coronavirus rules, reported Wales Online.
He asks the worshippers to leave the church, to pray and worship at home and to wait for the 17 days to "blow over."
A man who appears to be a member of the church, argues: "This is really strange and, I say it respectfully, we love you guys as police officers and we are not law-breaking people.
"But when they say to us that it is illegal to come and worship our God, this is the West, this isn't a nation somewhere far off somewhere else."
The officer replies: "As a Christian myself, I am not going to do that. I have a Christian family. My own mother is finding other ways to pray."
The group agreed to leave the building after police officers allowed them five minutes to finish their prayers.
A spokeswoman for South Wales Police said: "Police attended New Hope Community Church in Ball Road, Llanrumney, on Sunday afternoon, following a report of a Covid-19 breach.
"Officers followed the policing style which we have adopted throughout the pandemic of explaining the rules and encouraging people to comply.
"Officers moved outside the church to allow five minutes of prayer after which all those present left.
"No fixed penalty notices were issued.
"We know civil restrictions are frustrating and disheartening for people, but by following them, we can all play a part in protecting our communities and the National Health Service.
"Please take time to understand the latest regulations, all of which can be found on the Welsh Government website."
During the firebreak lockdown, places of worship are not allowed to be open to the public, according to the Welsh Government.
Churches and other religious spaces are only allowed to be open for weddings, civil partnership ceremonies or funerals - where people can attend at the invitation of the organiser.
Faith leaders, like priests, may access the place of worship to broadcast the service over the internet - but they can't take place with a congregation.
