Police are dealing with an incident close to Sheffield city centre this evening.
An area just off Savile Street has been cordoned off since about 7.30pm.
A passing motorist said he saw four police cars at the scene earlier.
A cordon is still in place and appears to be sealing off a patch of land and an industrial building.
Two police officers at the scene would not comment on the nature of the incident and would only say an investigating is ongoing.
Calls have been put into South Yorkshire Police headquarters and we are awaiting a response.
