A 28-year-old man was stabbed as he attempted to break up a fight after a house party on Machin Street in Bradwell on Friday, September 14.
Another man aged 49 was assaulted outside the Potter’s Wheel Pub and received facial injuries.
It is said that the group then dispersed in the area of Bradwell Lodge.
Officers have since arrested two teenage boys from Wolstanton and a 19-year-old man from Stoke on suspicion of wounding and violent disorder.
In the last two days two teenage boys from Knutton and Burslem have also been arrested.
All have been released under investigation while enquiries continue.
A section 35 dispersal order was also put in place in Bradwell by Chief Inspector Clair Langley, Newcastle Borough Local Policing Team Commander and will continue for the weekend ahead.
The order is used to direct a person away from an area to reduce the likelihood of crime or disorder and prevent members of the public being harassed, alarmed or distressed.
Chief Inspector Langley, said: “I want to reassure people in Bradwell we are increasing patrols in this area and have made good progress with this investigation.
“We have made five arrests to date, however enquiries are ongoing and we do need more witnesses to come forward and assist us with this investigation.
“I’m sure there are more witnesses, particularly in the area of the Britannia pub or Potter’s Wheel pub, who are yet to come forward and can either speak to my team or contact Crimestoppers anonymously.
“We will not tolerate violence on our streets and with the support of the community we will bring those responsible to justice.”
Anyone with information or who witnessed the incident is urged to call Staffordshire Police on 101 quoting reference number 927 of 14 September and this information will be passed to the Case Officer, DC Stubbs, Hanley CID.
