Parts of Croydon University Hospital were closed off after a woman was found with a "possible hazardous substance", according to the Metropolitan Police.

The Met was called at 03:46 BST by London Ambulance Service (LAS) to a report of a woman ingesting poison in Thornton Heath, south London.

It said she was taken to Croydon University Hospital and found to be in possession of a substance.

LAS and the Met say four of their staff have been exposed to the substance.

The Met added that two of its staff "remain under observation".

In a statement, the Met said the London Fire Brigade (LFB) also attended the hospital, adding "safety cordons and closures were established while specialist officers examined the item and safety procedures were enacted".

A spokesperson from LFB said crews from Norbury and Lewisham fire stations were called to the scene at 05:20.

They said firefighters "conducted a sweep of the premises to identify elevated readings of chemical substances" and "safely contained and removed a chemical from the scene".

Ambulances and emergency vehicles are being given access to the hospital throughout the incident response and earlier road closures have been lifted, the Met continued.
