Omaha police are investigating a pair of business robberies.  

Monday afternoon a lone gunman walked into the Mega Saver near 72nd and Military and demanded money.  

The suspect was last seen running toward some nearby apartments.  

Then, just before 9:00 p.m., two men armed with handguns held up the Taco John's near 83rd and Maple.  

After grabbing the cash they fled on foot to the south.  

No arrests have been made in either hold up.
