A 25-year-old Muncie man is suspected of leaving a backpack containing a mobile meth lab inside a Wal-Mart restroom last week.
The Indiana State Police says Tyler Armstrong was arrested Monday night. He's expected to be charged with manufacturing methamphetamine, dumping controlled substance waste and criminal recklessness.
Police said Armstrong also will be charged with battery on a police officer and resisting law enforcement because of an altercation during his arrest.
Twenty-four-year-old Ashley Oliver was arrested with Armstrong on a preliminary charge of aiding in the manufacture of methamphetamine.
Both suspects were booked into the Delaware County Jail. Armstrong is being held on $12,500 bond, and Oliver's bond is set at $5,000.
Online jail records don't list an attorney for either of them.
