A police and crime commissioner has decried an "outrageous" attack on an officer who needed stitches to his head after he was hit while trying to break up a party that was allegedly breaking lockdown rules.
Around 20 people were reported as not observing social distancing rules at the party in Underwood Close, Luton on 13 June.
As they attempted to break the gathering up, one of the two officers had a drink thrown in his face by a man and was then hit over the head with an object.
The officer was taken to hospital, where he received stitches to his head wound. The other officer had minor injuries.
Bedfordshire PCC Kathryn Holloway said: "It is outrageous that a police officer who was acting to protect the wider public with regard to the deadly risks presented by the coronavirus should have been attacked and injured in this way.
"A vicious assault of one of our officers is not part of the job and is wholly unacceptable in any circumstances but, especially, in those represented by the current emergency."
Two women in their 20s, a man in his 20s and an 18-year-old man were arrested and have been released under investigation.
