A southwestern Missouri man is accused of injuring a couple by throwing acid on them during a confrontation.

The Springfield News-Leader reports that 27-year-old Joseph Mangione was charged Tuesday in Greene County with second-degree assault.

Authorities allege in a probable cause statement that the couple confronted the bicycle-riding Mangione on Sunday about an earlier incident in which he allegedly sprayed the woman with pepper spray.

Investigators say that's when Mangione thrust a bottle at the man, spilling suspected acid on the couple.

The victims were treated for chemical burns at a hospital.

Mangione told police the couple had hit him with their car and that he never threw acid on anyone.

Online court records don't show whether he has an attorney.
