Eight police cars and a van swooped on a business on Staniforth Road in Darnall shortly after 4pm this afternoon.
Crowds of people watched as officers entered the property before bringing a man out and escorting him into a police car.
One eyewitness told the Star that police had told him they were arresting a ‘dangerous individual’.
South Yorkshire Police confirmed they had attended the property and had arrested one man.
The operation came about after on duty officers spotted a man they believed to be wanted in connection with previous offences, they added.
