A major acid leak in Hull has caused a "vapour cloud" over residential areas, sparking concern.
The leak stemmed from a tank containing 580 tonnes of hydrochloric acid at the King George dock on the evening of 18 September. Fifty firefighters responded to the incident.
Residents of the area were not evacuated and instead advised to stay indoors with doors and windows shut.
Details are still emerging from this incident and will be reported on when released.
