Two men were arrested Thursday in connection with a string of armed robberies on Wednesday and Thursday on the north side of Indianapolis. Jeffrey Tullis, 21, and Stanley Jackson, 20, are accused of at least four robberies. In each case, the suspects allegedly took personal items and wallets from victims at gunpoint. They were taken into custody after somebody reported a suspicious vehicle on the side of the road in the 2400 block of North Alabama Street. Police found the men in the vehicle and recovered two unlicensed handguns and items stolen from the victims.
