Four people have been taken to hospital after emergency services were called to reports of a “chemical smell” in Wimbledon.

Three men and a woman were transported for further treatment while paramedics assessed eight other patients at the scene, though they weren’t taken to hospital.

The incident happened near to a bank in Wimbledon Hill Road, at around 12.30pm on April 10 as police, paramedics and the fire brigade were in attendance.

It’s unclear at this stage what the current conditions are for the people who were taken to hospital.

Scotland Yard say the incident is not believed to be suspicious and the London Fire Brigade said they would do a sweep of the building using its detection equipment.

Several images and videos shared on social media show ambulance crews’ vehicles and fire engines parked along Alexandra Road.

Eyewitness Omar Loveridge said: “I was having coffee at Starbucks when, at around 12.40pm, the first fire engine arrived on scene followed by a barrage of paramedics and ambulances and then a police van.

“They were entering an alleyway next to Lagoon.”

The London Fire Brigade said they were called to reports of a chemical smell at a bank and offices shortly after 12.30pm on April 10.

A statement added: “Firefighters carried out a sweep of the property but found no elevated readings. The cause of the incident is believed to be fumigation of the building, which had taken place overnight.”

The bridge said the incident was over just past 2.20pm as they sent two engines from Mitcham and Wimbledon fire stations, as well as two fire rescue units from Bethnal Green and Lewisham stations.
