KNOXVILLE, Tenn. (WATE) — Investigations into what officials believe are suspicious fires are underway after Knoxville Fire Department crews worked three separate incidents along Clinton Highway early Friday.

According to KFD Assistant Chief G. Brent Seymour, at around 5:23 a.m. Friday KFD responded to the three separate fires in the 5000 block of Clinton Highway area. Seymour said as units were responding to the first reported fire in a trash receptacle at a vacant building, they noticed another fire behind BinMayhem at 5032 Clinton Highway in the same parking lot.

Seymour says that the fire had extended into the roof of the structure from the back wall. Then, an additional fire was reported at Inskip Ball Park a short time later.

No injuries to civilian or firefighting personnel were reported, Seymour said. KFD fire Investigators remained on the scene to examine the incidents. The fires are considered suspicious at this time.
