Three police officers were injured after a fight broke out at a pub.
A group of people were reported to be fighting following an argument, which spilled outside into the car park.
Three response officers suffered minor injuries, including one who was bitten on the leg, while trying to detain one of the suspects.
Officers arrested two people and a number of people dispersed during the incident at The Rose Inn, Moor Road, Strelley, at 12.50am today (Sunday 23 January).
A knife was also reportedly brandished during the incident, and officers recovered a knife.
Two men, aged 39 and 36, were arrested on suspicion of affray and police assault. The 36-year-old was also arrested on suspicion of possession of a bladed article.
A police officer was also bitten and spat on during a separate incident after stopping a car as part of routine road traffic enquiries.
A 56-year-old man was arrested on suspicion of drink-driving, driving without a licence or insurance, and assaulting a police officer following the incident in Great North Road, Gamston, near Tuxford.
Another man who was in the car was also being arrested when he ran off. Officers later arrested a 57-year-old man on suspicion of evading police custody.
Sergeant Howard Kirkland, of Nottinghamshire Police, said: “Assaults on police officers are totally unacceptable. Officers are members of the community like anyone else, who have family members and colleagues who are concerned for their wellbeing.
“They pull on the uniform each day to do an extraordinary public service to keep the people of Nottinghamshire safe, so it is always saddening to hear when they are hurt while doing that.
“Any assaults on emergency workers are treated very seriously and we will always look to put people before the courts as soon as we can if they are suspected of offences like this.”
