A Nottinghamshire Police officer was bitten on his right arm as he tried to detain a man.
Officers were called to Heddington Gardens in Arnold at around 6.50pm on Sunday following reports of a domestic. Police Sergeant Neil Langham is leading the investigation.
He said: “Whilst being restrained and handcuffed, he has bitten the right bicep of the attending officer, causing a visible injury.
“A 19-year-old man has been arrested on suspicion of assaulting an emergency worker and breaching his electronic tag. He remains in police custody for questioning.
“Officer assaults are totally unacceptable.
“Every day, our officers put themselves at risk to help protect the safety of the public and sadly, that can sometimes lead to incidents where police are injured.
“We take these incidents very seriously and will ensure that they are investigated thoroughly. Appropriate action will then be taken against those who are found to be guilty of such offences.
“Thankfully, the officers in this incident were not seriously hurt.”
