Shortly before 6:30am on the morning of Sunday 30 June 2019, there was a disturbance involving a number of men on Bradshawgate which resulted in an 18-year-old man being seriously injured.
The man was taken to hospital as a result and he remains there in a critical condition.
Three men, aged 18, 22 and 23, were arrested on suspicion of causing grievous bodily harm with intent and violent disorder. One man has since been charged whilst two have been released on police bail.

It is believed that there are possibly a number of witnesses to the disorder, some of whom may have captured footage on their mobile phones.
