South Western Ambulance Service was called to Stall Street in the city centre, near the Roman Baths, at around 2.30pm yesterday afternoon, Monday 29th July, and were told a woman who had a plastic bag had approached a number of people who then reported feeling ill.
Police were brought in at 3.08pm, and a cordon was set up around the scene. A large emergency service response saw many surrounding roads blocked by vehicles.
Emergency crews in hazmat treated members of the public at the scene, along with firefighters.
A member of the public was seen to be hosed off by fire crews in a makeshift tarpaulin area.
The Roman Baths remained open throughout the incident, though shops on Stall Street including Primark were evacuated.

The ambulance service initially informed told police they had taken two people to hospital, but ultimately only one woman needed to be conveyed after experiencing breathing difficulties and itchy eyes.
She was checked over and discharged later in the evening.
The scene was lifted shortly before 8pm after the area had been checked, and the fire service conducted an air quality test. No trace of any chemical or hazardous substance was found.

CCTV enquiries were carried out to identify the individual who was in possession of the plastic bag at the time of the incident. A 73-year-old was subsequently arrested on suspicion of administering an unknown noxious substance.
Chief Inspector Scott Hill, of the Bath Neighbourhood Policing Team, said: “We’d like to thank the public for their patience and understanding while we dealt with an incident in Bath yesterday.
“Public safety is always our top priority and we implemented well-rehearsed plans to ensure this isolated incident was dealt with as swiftly and effectively as possible.
“All emergency services have a duty of care to their staff and so a decision was made to wear protective clothing while there was uncertainty about what we were dealing with.
“Further enquiries will be required to fully understand what caused some people to experience feeling unwell, but to help us progress that work we have made an arrest as we seek to establish whether any offence has been committed.
“We can confirm thorough testing of the surrounding public area was carried out before the cordon was lifted which confirmed there were no traces of any chemical substance.
“We are aware there was speculation on social media yesterday about this and hope confirming this provides reassurance to the public.
“We are not aware of there being any increased risk to the public but officers will be on patrol in the city centre today if anyone wishes to speak with us directly to raise any concerns they may have.”
