Violent and disruptive behaviour in the centre of Nottingham is being targeted with the creation of dispersal zones.
The police are setting up the zones in the Old Market Square and Broadway in the Lace Market from Friday night.
People can be asked to leave the area and face arrest if they return within 24 hours. Between 9pm and 6am under 16s can be escorted home by officers.
The move has been initiated by police who have attended a number of incidents over the past three months.
Inspector Paul Winter, from Central police station, said: "Resources have been sent to deal with groups hanging around these locations, who have been intimidating business staff and their customers.
"Threats of violence have also required a police response."
Ashley Walters, from the Geisha bar in the Lace Market, said: "This is great news. It's often the case that late in the evening people have had too much to drink and cause a lot of noise and disruption.
"This should help the Lace Market get back to what it should be - a discerning venue for drinkers and diners."
The orders will last for six months.
