An armored truck guard was shot in the leg during a robbery in northwest Miami-Dade County.

The robbery occurred Friday morning at Check Cashing USA, 2905 NW 27th Ave.

Miami-Dade police said the Brinks guard was expected to be OK.

Local 10 News crime reporter John Turchin said the Brinks truck was making a money delivery to the check-cashing business when a man pushed the 72-year-old guard to the ground and shot him.
