Mexico City's mayor says a baby boy born in one of the city's subway stations will be allowed to ride the trains free for life.
The baby's 22-year-old mother was trying to take the subway to the hospital when she went into labour on Tuesday.
Subway employees, police and paramedics helped her give birth in an entrance to a subway platform.
Mayor Miguel Angel Mancera wrote in his Twitter account on Tuesday that the yet-unnamed boy will have the right to ride the subway free for life.
Subway tickets in Mexico City cost three pesos (25 cents) for an unlimited ride.
