A police cordon and multiple road closures are continuing in the High Green area of north Sheffield, immediately north of Chapeltown, after a search operation that began last Friday led to a 36-year-old local woman being charged under the Explosive Substances Act 1883 and evacuations of nearby homes. Here is what South Yorkshire Police has confirmed so far.

A note on location before the detail: South Yorkshire Police’s statements and local reporting place this incident on Mapplebeck Road in High Green, a village in the West Ecclesfield ward of Sheffield, roughly a mile north of Chapeltown itself and served by Chapeltown railway station. It sits within the same S35 postal district and immediate area as Chapeltown, which is likely why the incident has been associated with Chapeltown in public discussion, but the affected streets are in High Green specifically.

What has happened

South Yorkshire Police confirmed that officers have had a presence at a house on Mapplebeck Road since Friday, 11 September, as part of a forensic search connected to an investigation into potential explosive substances. The search was described by the force as being conducted carefully by specialist officers over several days.

On Monday, 14 September, a 36-year-old woman, High Green, appeared in court charged with an offence under Section 4 of the Explosive Substances Act 1883. She was remanded in custody.

The investigation escalated the following day. According to South Yorkshire Police, the discovery of “additional items in a concealed area” on the afternoon of Tuesday, 15 September, made it necessary to evacuate a number of nearby properties “to enable emergency services and specialists to ensure safety.” A 100-metre cordon was established around the property, and residents advised to leave their homes were directed to a nearby rest centre.

Police have stressed that no injuries have been reported at any point in the operation, and that other emergency services attended as a precaution rather than in response to any incident on scene.

Roads currently affected

Road closures have been confirmed on the following streets in High Green:

  • Mapplebeck Road
  • Griffiths Road
  • School Road
  • Green Gate Lane
  • Worrall Road
  • Beechwood Road
  • Hawthorne Road
  • Entwhistle Road
  • Greenwood Road

As of Wednesday morning, 16 September, South Yorkshire Police said the cordon was expected to remain in place throughout the day while emergency services and specialist agencies continue work to ensure the affected property and surrounding homes are safe.

What police have said

Assistant Chief Constable Ian Proffitt, named by the force as Gold Command for the operation, issued a statement addressing the impact on residents directly: “We don’t underestimate the impact this has had on those affected and want to thank residents for their continued patience, understanding and cooperation.” He added that active court proceedings limited what the force could say publicly about the details of the investigation, but that the operation was being carried out “for your safety.”

The statement confirmed that emergency services, the local authority, health partners and other agencies have been working together throughout the incident to support displaced residents.

What remains unconfirmed

South Yorkshire Police has not published further detail on the nature of the items recovered from the property, the scale of the forensic search, or an estimated timeframe for when the cordon and remaining road closures will be lifted. Some early wire reports gave the woman’s age as 35 rather than 36; the majority of confirmed reporting, drawing on the same police statements, records her age as 36. This article will be updated as South Yorkshire Police issues further statements.

Anyone in the affected area is advised to follow South Yorkshire Police’s official channels for the latest confirmed road closure and cordon information, and to avoid the immediate vicinity of Mapplebeck Road until the cordon is lifted.
