FORT WAYNE, Ind. (WFFT) -- Police say a bystander armed with a gun kept a brutal baseball bat beating on Saturday from being even worse.

Fort Wayne police say the bystander pulled out a gun when they saw a masked man beating the victim in the Glen Apple Walmart parking lot just before 10:30 a.m.

That's when police say the man got back into his burgundy Chevy Impala and drove away.

A detective spotted the vehicle and tried to pull it over but was unsuccessful. Police say officers in Wells County also tried to pull it over but couldn't.

Investigators later arrested and charged 21-year-old Levi Arnold of Bluffton with attempted murder.

Police say they were tipped off by Arnold by someone who recognized the car from a separate incident.

Sgt. Sofia Rosales-Scatena says they don't believe it was a hate crime, nor do they believe the two knew each other. Instead, they say, it appears Arnold just snapped.
