FORT WAYNE, Ind. (WANE) — An explosion rocked a Fort Wayne biotechnology company on the city’s south side early Wednesday.

Firefighters were called just after 6:30 a.m. to Biodyne USA at 10617 Majic Port Lane, in the area of West Ferguson and Bluffton roads near the Fort Wayne International Airport. Employees from nearby business — Brown Equipment Company Incorporated — noticed debris on their lawn, authorities said.

Allen County Fire District Chief Don Patnoude said Wednesday that a high-pressure water tank inside Biodyne USA exploded, blowing off a portion of the roof. A section of the roof of the building could be seen missing, and its garage door was left crumpled.

No one was inside the building at the time of the explosion, and no one was hurt. The building never caught fire.

According to its website, Biodyne USA is “an environmental biotechnology company focused on harnessing the power of naturally occurring, beneficial microorganisms and other sustainable technologies for use in a variety of agricultural and environmental applications.”
