Mexican authorities say armed men have stolen some 157 million pesos from a cash transporting company in southern Mexico.
The Oaxaca state attorney general's office says six gunmen wearing masks and latex gloves broke into the Cometra facility, subdued four guards and made off with cash equivalent to about $13 million.
No one was hurt in the heist early Sunday.
The attorney general's office says the robbers apparently wore uniforms of Cometra workers and drove a vehicle with the company logo.
The statement released no other details and it isn't clear if authorities suspect the theft was an inside job.
Criminal gangs in Mexico often have police or other security uniforms, some stolen and others fake.
