A personal security backpack emits visual and audio alarm signals for attracting attention to a crime scene or crisis situation powered by a portable battery pack and contained within a separate, readily accessible component compartment of the backpack. Two shoulder straps and a spacious main compartment for holding personal items are provided. The multi-alarm system remains concealed under an openable access flap that covers the entire component compartment. A smaller, rectangular flap section may be folded underneath the access flap to reveal a rectangular visual window in the component compartment. Two siren signal generators and a visual signal generator are disposed within the backpack proximate openings for generating loud distinguishable noise and a visual signal, with the sirens being unmuffled and pointed in opposite directions. A panic switch is mounted on the backpack's shoulder strap to provide easy access for activating the sirens and visual signal simultaneously. An adjustable anti-theft strap fastens across the chest, from one shoulder strap to the other, preventing the personal security backpack from easily being taken from the user.
