A teenage boy and a woman in their 60s were injured after a knife attack by young people in the city center.
The scary incident happened in broad daylight in front of shocked shoppers in the Canal Walk this afternoon.
The boy was taken to hospital with a suspected stab wound after being assaulted by a number of youths. His injuries are not believed to be life-threatening.
SUMMARY: Police rush to the scene of stabbing in the center
A woman in her 60s was also caught by the incident and sustained minor injuries that did not require hospital treatment.
Police were alerted after hearing of an altercation between two groups outside Foot Asylum in The Parade at 3.30pm. The victim was then chased to nearby JD Sports, where he was stabbed.
Witnesses reported hearing the scream and then watching six police cars and an ambulance show up at the scene.
A man was standing on the other side of the street when he heard screams.
He said, “It’s absolutely awful. I just heard screams and saw sirens.
“It happened right between Christmas and New Year, which is incredible.”
One woman added: “It’s awful that it’s come this far. It’s so scary that that kind of thing happens in the middle of the day in the middle of the city.”
Another said, “I just really hope they are all okay. It’s absolutely awful, and it was in broad daylight.”
About an hour after the incident took place, staff at JD Sports were seen standing outside the store pointing to areas for police.
Officers taped a barricade inside the store and an area outside in the middle of the street parallel to EE, Three and JD Sports.
Benches and trees were within the taped area, but the entrance to JD Sports was not built-in.
The Canal Walk was quite busy just an hour after the incident when shoppers took home their great deals after Christmas.
People slowed down when they saw the tape and the police presence to ask officers and other shoppers what had happened there.
There was a sense of fear and shock that such an incident could have happened in the middle of the day.
Some shops on the Canal Walk closed early, while others remained open despite everything that had taken place outside their shop windows.
Police are now looking for witnesses to the assault and would especially like to hear from anyone who may have recorded footage of this incident.
Anyone with information should call the police on 101.
