South Yorkshire Police are appealing for witnesses after seven people were stabbed in separate incidents on Saturday and Sunday in Sheffield city centre. Two men have been charged in connection with altercations on Carver Street and Division Street in which five people were injured in the early hours of Saturday morning. At around 2.20am on Sunday, officers attended and secured a scene at the Area bar on Burgess Street where two men had been stabbed in what the police believe to be an unrelated incident. A closure notice has been served on the Area bar which the police are seeking to extend at the magistrates court. Baillor Jalloh reports for Sheffield Live!
