Police say Adam Robert David, of Pottstown, confessed to robbing the Kiwi Yogurt store at the Providence Towne Center in Upper Providence Township back on July 30th.
In that robbery, the suspect is seen on surveillance video entering the store shortly after it opened at noon, wielding what appeared to be a machine gun - police later said it was an 'assault-style' BB gun.
After failing to get any money out of the safe, police say David stole about $300 from the register and drove off in a blue Audi.
After confessing to the robbery, police say David also confessed to stealing the Audi from a home in Embreeville, Chester County.
A Lower Pottsgrove police officer spotted the Audi shortly after the robbery and gave chase, but David eluded capture. Investigators say David then ditched the car in a field.
David was already in custody, arrested following the robbery of the Domino's Pizza on Lancaster Avenue in Radnor Township on Wednesday night. Police say David used another BB gun in that case and fled the store on foot.
The Delaware County and Chester County District Attorney's Offices have agreed to allow the Montgomery County District Attorney's Office prosecute the defendant.
David appeared in court on Monday, charged with robbery, assault and other felony offenses. The judge handed down a $500,000 cash bail.
Police say David never told them why he committed the crimes, but in court on Monday he told the judge he suffers from mental illness and stopped taking his medication a couple of months ago.
