Akron police are investigating a robbery at a McDonald’s restaurant Saturday night. Around 640pm, officers responded to a call in the 500 block of East Market Street. According to the manager, she gave a would-be customer correct change back from a purchase, however the customer said he was short-changed. After the manager declined to provide the suspect with additional money, he shoved her to the ground, reached into the register, and took an undisclosed amount of money from the drawer. Witnesses intervened and attempted to restrain the suspect, but he managed to break free and take off before police arrived. Anyone with information, call Akron police at 330-375-2490. The manager was not seriously hurt.
