VIDEO: Mysterious plume of steam spews from the ground in Sheffield city centre
Steam continues to issue from the ground after appearing at a spot in Sheffield city centre more than a week ago.
The plume is next to Arundel Gate Interchange on Norfolk Street, a few metres away from the Crucible Theatre.
The area has been fenced off with signs on metal barriers reading 'Danger Keep Out' and 'Deep Excavation'.
The Star has been told the steam has been billowing out of the ground for more than a week.
The cause is being investigated.
Sinkholes caused havoc in Sheffield earlier this year. A section of Hutcliffe Wood Road collapsed without warning in April and a steaming hole appeared outside Pond Street Interchange in May.
