WICHITA, Kan. (AP) — Wichita authorities say there are no major injuries and no environmental damage after a tanker overturned near downtown but didn’t spill its contents.

Acting Battalion Chief Chad Winton tells KAKE-TV the tanker on Thursday evening was carrying 5,000 gallons of an oil additive that isn’t very toxic. He says none of the substance spilled.

Witnesses say the tanker overturned while the driver attempted to make a U-turn.

The driver suffered minor injuries. The driver’s identity hasn’t been released.

No charges have been reported.
