Points of Crime Prevention

Purse Snatching

  "Impossible! How could this happen to me..." is how most victims of purse-snatching start their stories. If you begin with the mindset, "They are after me.." and undertake some trifling anti-theft measures, you can reduce your chances of being victimized.

Points of Crime Prevention


  • Hold your bag or luggage on the opposit side of the roadway.
  • Avoid walking on quiet back streets. Walk on busy main streets as much as possible.
  • Have a cover (crime prevention net, etc.) on the carrier or basket of your bicycle.
  • Be careful of motorcycles and bicycles coming from behind you.
  • Stop talking on the phone, or writing emails while walking; it is incredibly dangerous as it distracts you from your surroundings.

Bicycle / Motorcycle Theft

Points of Crime Prevention

  • Attach multiple locks to your bike.
  • When parking your motorcycle, do not forget to remove the ignition key, lock the handlebars, and place a wire lock (or a bar lock) on your motorcycle.
  • Park your motorcycle in a designated parking place, not on the road.

Points of Crime Prevention

Be sure to properly close your doors! Everything starts with being sure your doors are properly closed!

  • Even if you are just stepping out for a second to throw out your garbage, be absolutely certain to close and lock your doors.
  • Be sure that ALL entrances to your property are shut, including even small windows (like the one in many bathrooms).
  • Even if it is "just the balcony", you must lock and shut it; no exceptions!
  • Before going out or going to sleep, inspect each door and window and ensure that they are all locked and closed.

The Building Perimeter

  • Maintain a mesh-type fence that ensures an unobstructed view of the surroundings
  • Trim all shrubs to make sure there is no hiding place for suspicious people.
  • Install sensor lighting to automatically illuminate dark places when someone enters your secure perimeter.
  • Increase your surveillance ability by installing security cameras.
  • Keep a dog and spread gravel around your secure perimeter; the gravel will produce noise, and the dog will make it difficult for them to get near your property.
  • Leaving nothing outside that could be used to penetrate your secure perimeter (Garbage cans, ladders)

The Entrance ⁄ Kitchen Door ⁄ Etc...

  • Switch the door and locks with anti-theft material that is difficult to destroy.
  • Keep a light by your gate, and turn it on regularly when it becomes dark.
  • Don't let them know you are away by letting the newspaper ⁄ mail pile up in the mailbox.

Windows ⁄ Sash

  • Use anti-theft glass that is difficult to destroy
  • Apply anti-theft film to existing glass to increase the difficulty in burglarizing your property.
  • Install a Sash lock
  • Waist-high windows should be fitted with crystal-lattice patterning.
  • Install an auxiliary lock in addition to the normal crescent lock. This auxiliary should ideally be located above and below the sash
  • Install a window buzzer that sounds an alarm if the glass is broken.

When you return to the house.

  • Even if it is longer, take a bright road with more people on it.
  • Stop talking on the phone, or listening to music through earphones while walking; it is incredibly dangerous as it distracts you from your surroundings.
  • If it is very late, have someone from home meet you at the station or call a taxi.
  • Just in case, keep a crime-prevention buzzer in your bag and carry it in your hand while walking.

For girls living alone

When entering the house.

  • Before opening the door, pay careful attention to make sure there are no suspicious persons in your vicinity.
  • When opening the door, swiftly dash inside and immediately lock the door behind you.
  • Be sure to say "I'm home" in a loud voice if you are returning home.

Before Sleeping

  • Make sure that the door and easy-to-enter locations are closed and locked.
    *Even the balcony should be closed; there are examples of people entering from the balcony, even when it is one floor up.

For Visitors..

  • Confirm the identity of the visitor before opening the door.
  • Talk to the person without removing the door chain.
    * ( If the person claims to be from a delivery company, confirm the sender and the item being delivered )
