A kilogram of suspicious powder and liquid dumped on a pavement in Gospel Oak sparked an investigation by the London Fire Brigade this morning.

Three fire engines and fire officers were called to Gordon House Road at 8.40am after passers-by spotted potentially hazardous chemical powder fly-tipped on the side of the road.

A 25m hazard zone around the scene was cordoned off to the public as a precaution.

Following some tests, the power and liquid was found to be non-hazardous. Camden Council is now responsible for its clean-up.
