A Port St. Lucie father is arrested after police find a loaded gun under his 6-year-old daughter's pillow.

Police arrested Robert Johnson on suspicion of child abuse and domestic battery. Police were called to his home because of a fight between Johnson and his stepfather.

While they investigated, they found the handgun in the girl's bed. When police asked why the gun was there, Johnson told them he's worried about home invasions.
