Investigators said they believe the pair were involved in four crimes in Durham reported on Oct. 7.
It started around 7:30 p.m. when a woman taking out trash in the 1500 block of South Roxboro Street said she was confronted by two men in a small white car. The passenger got out of the car and robbed her at gunpoint of her phone, cigarettes and other items.
About 30 minutes later, a woman was getting out of her car in a parking lot in the 3700 block of Southwest Durham Drive when a small white car with two men inside, pulled up behind her. One of the men robbed her of her purse at gunpoint and told her to lie on the ground.
A short time later, a woman was in a parked car in the parking lot of Hardees at 2721 Chapel Hill Road when a man armed with a gun tapped on her window. The woman told police she blew her horn several times, scaring the man away. The man and a second man fled in a small white car.
