We’re appealing to trace three men who stopped to help during an assault in Station Street.
The assault happened at around 5.20pm on Friday 4 December near Balti Towers restaurant and left the victim, a 20-year-old man from Burton, with a serious leg wound.
The victim received treatment at Queen’s Hospital Burton but is now recovering at home.
A 17-year-old male arrested on suspicion of causing grievous bodily harm has been released on bail pending further enquires.
DS Neil Poultney said: “Our inquiries have established that three smartly dressed men stopped to intervene while the incident was ongoing.
“We are really keen to trace these good samaritans as it is likely they are witnesses to the incident.
“They’re described as two black men and a white man, aged in their 20s or 30s, and they were all dressed in smart office wear.
“They were walking from Burton town centre towards the railway station so it is possible they were commuters on their way home, going back towards either Derby or Birmingham.
“Our investigation into the incident is ongoing with continued enquiries in the area to secure CCTV evidence and speak to witnesses.”
