- Engineers said checks at the site and nearby areas found no evidence of gas or a leak, describing the odour as an 'eggy' smell.
- Tesco Express staff left the store as a precaution before engineers arrived, and the shop reopened after investigations concluded.
- Residents, including Grace Scott, reported a strong smell along the high street and contacted the emergency gas line.
