More than 200 people had to leave a drugs plant in West Sussex after fire broke out in a research laboratory.
Firefighters from Sussex and Surrey were called to the incident at Novartis in Horsham and stayed at the scene for several hours on Thursday.
A spokeswoman from the pharmaceutical firm said it had been a major incident.
The blaze broke out on the third floor of the building in Wimblehurst Road. Crews said the cause of the fire was being investigated.

"All of our employees were safely evacuated from the building.
"The safety of our employees is our top priority and we are thankful that no-one was injured in this incident."
