A man suffered serious injuries after he was reportedly hit over the head with a baseball bat.
Police were called to an address in Calverton, shortly after 1 am this morning after a man was found to have been assaulted.
The victim, a man in his 30s, remains in hospital at the Queen’s Medical Centre where he is being treated for a serious head injury.
A 51-year-old man was arrested shortly afterwards on suspicion of assault and remains in police custody.
Detective Sergeant Charlotte Henson, of Nottinghamshire Police, said: “This was a nasty assault that has resulted in a serious injury to the victim. This kind of violence is completely unacceptable and I am determined to get to the bottom of what happened here.
“If you have any information that may assist our investigation please call 101 quoting incident 43 of Sunday 5 September.”
