Fuerza Pública officers shot it out with three robbers who had forced their way into a Santa Ana home early Thursday.
Officers detained a 17-year-old suspect who suffered a bullet wound of the forearm, they said.
The Judicial Investigating Organization said that three robbers forced a window at the home in order to enter. They did so without realizing that a woman occupant was there, said agents. The woman had the presence of mind to call police and to hide herself in the house.
However, the robbers realized the woman was there and tried to open the door behind which she hid, agents said. That is when Fuerza Pública officers arrived and engaged the robbers in a firefight.
At least two robbers fled, the Fuerza Pública reported.
