Shocking footage has emerged showing a Colorado restaurant packed with diners for Mother's Day, in defiance of the state's lockdown rules. 

Video taken inside Castle Rock's C&C Coffee and Kitchen and shared online shows crowds of people waiting for their food, enjoying drinks at tables and sitting close by to one another, many without masks.  

In a Facebook live video owner April Arellano thanked everyone for their support, showing off her packed restaurant. She added: 'So much for some of those people saying nobody would show up.'

But Colorado Gov. Jared Polis' office slammed the footage, saying: 'These restaurants are not only breaking the law, they are endangering the lives of their staff, customers and community.'  

Restaurants and bars in the state are still limited to takeout only with social distancing restrictions. In the footage people appear to be drinking coffees and drinks at tables inside the restaurant. 

Sharing the footage online, Nick Puckett wrote: 'Happy Mother's Day from C& C in Castle Rock, where the owner said this is almost double a normal Mother's Day.'
