Sussex Police have concluded enquiries into a hazardous material incident in Worthing on Sunday (11 August).
Following extensive searches of the seafront, including a drone and foot patrols, there was no evidence of anything that led to a reasonable explanation of what happened.
As a result of this, we are satisfied we have explored all lines of enquiry and there is no further involvement for police.
A small number of people reported symptoms including sore eyes and vomiting, two of whom were taken to hospital and later discharged.
We’d like to thank everyone for their patience and understanding while police cordons were in place.
Anyone with any concerns is asked to contact Adur and Worthing Council’s public health team on 01903 221064 or visit their website.
