Mobile police spokeswoman Maj. Kara Fagan says the first holdup took place Monday afternoon at a barber shop.
She says both robbers were armed with handguns and ran south after taking cash from the store.
Fagan says about an hour later, a woman was robbed at gunpoint of her purse outside a home in southwest Mobile, and a Subway restaurant was held up a short time later by what police said was the same couple.
Fagan says the robbers are believed to be 16 to 19 years old.
