The Reno Police Department says some help from the public led to the arrest of a Reno man on two counts of attempted robbery and two counts of attempted burglary. 50 year old Troy Dittmer was booked into the Washoe County jail. Dittmer allegedly tried to rob a check cashing business on Warren Way about 3 p.m. Wednesday, while armed with a stun gun. He didn't get any money, and was seen leaving in a white Chrysler Pacifica. At 3:30 p.m. there was a report of citizens detaining a robbery suspect in the 300 block of East Plumb Lane. Police arrived to find Dittmer being held down by two citizens, who grabbed him despite being zapped by the stun gun.
