High-visibility patrols continue to operate in the city centre to offer public reassurance following a confrontation between two groups involving weapons.
Police have arrested seven people in connection with the incident on Sunday 16 November, with strict bail conditions not to enter the city or wear face coverings.
The investigation continues.
Since additional patrols have been deployed, officers have made 41 arrests in the Old Market Square area.
The offences include three arrests for carrying a bladed article, a number of arrests for possession of drugs including five arrests for possession with intent to supply, two arrests for an attempted robbery and two arrests for drunk and disorderly.
Assistant Chief Constable Suk Verma said:
“Last week, I was clear that we will not tolerate people coming into the city to commit crime.
“Enough is enough. We cannot let the minority make the majority feel unsafe and so we are taking a zero tolerance approach to criminality.
“We have always had visibility on the Old Market Square but hope the additional high-visibility patrols deployed in the area and the surrounding streets will offer the public the reassurance they deserve.
“In the last seven days, we have made 41 arrests in this area, which sends out a very clear message to those who wish to come into Nottingham to commit crime.
“A number of these incidents saw the suspects caught very quickly thanks to the patrols we have in place.
“We want the city to be a no-go area for anyone who wishes to commit crime by making the environment as hostile as possible for them.
“And if that is not enough of a deterrent, and you still wish to commit crime, then rest assured, we will use all the powers at our disposal to put you before the courts and ensure you cannot come into Nottingham city centre again.”
