Park Square siege: Everything we know about police incident at flats after nearly 24 hours

Negotiators

Negotiators continue to talk to a man claiming to have “weapons and explosives" in The Gateway flats on Broad Street.

Armed police

Armed police were initially called at 7pm on Monday evening. At 4pm on Tuesday South Yorkshire Police said Sheffield Parkway between Park Square roundabout and Derek Dooley Way remained closed in both directions “while specialist officers continue to negotiate with the man.”

Congestion

It means congestion is set to build as rush hour approaches, especially on Derek Dooley Way which is now the main route out of the city to the Parkway. Thousands of commuters were affected by the closures this morning with some spending three hours trying to get to work.

At 5pm on Tuesday, Supertram posted: “Due to the ongoing police incident in Sheffield city centre we are still unable to provide a full service across the network....Thank you for your continued patience.”

Cordon

Star reporter Alastair Ulke, reporting from the scene, said it was the largest police cordon he’d ever seen and Sheffield was “at a standstill.”

Evacuated

The Gateway residents were evacuated and spent the night at Pond's Forge sports centre

The incident also affected students living in the Pinnacles flats, which neighbours the Gateway apartments.
