Emergency services were called to Lowtown Street just after 7pm on 26th January where a 51-year-old woman received head injuries following a disagreement between a small group of people who knew each other.
Police say that a man was also hospitalised who is thought to have been hit with a hammer.
He is in a stable condition.
A 26-year-old arrested on suspicion of assault has since been released from custody and is on police bail pending further enquiries.
Witnesses or anyone with any information should call Nottinghamshire Police on 101 or call Crimestoppers anonymously on 0800 555 111 .
