At least one person was injured after a fire broke out following an explosion at a pharma company in JN Pharma city, Visakhapatnam on Monday night. The incident took place at Coastal Waste Management Project, a unit of Ramky Solvents, PTI reported quoting sources.

The blasts were experienced by residents in the Paravada area, triggering panic, as it came just over a couple of months after the styrene vapour leak in the LG Polymers plant in the region which killed 12 and sickened hundreds.

One worker sustained burn injuries, at least nine fire tenders were being pressed into service to put out the massive blaze.

The cause of the incident is not yet known, police sources said.

Last month,  a gas leak incident in one of the companies in the Pharma City had left two workers dead and four injured.
