The most prevalent crime on the

Upper West Side of Manhattan is

Theft of Unattended Property.

An unfortunate result of the dramatic decrease in crime in NYC is the false sense of security people have about leaving their pocketbooks, shopping bags, brief cases, laptop computers, and other property unattended.

The 20th Precinct Community Council has compiled this list of precautionary tips:

 In restaurants, no matter how “upscale” or expensive the establishment, do not hang your purse over the back of your chair. Keep it on your lap or between your feet under your table. Restaurant purse theft is one of the most prevalent crimes in this area;

 When carrying a purse, keep it close to your body and under your arm (carry it like a football) to prevent purse-snatchings; and beware of pick-pockets -- do not leave your purse open simply because you are on the cell phone or listening to your MP3.

 Do not leave any property, such as a computer, shopping bag, briefcase or jacket, unattended anywhere: it only takes a moment for someone to snatch your item and run. Do not ask a stranger to “watch it” for you.

Car owners should avoid leaving packages within plain view inside the car. It’s an enticement to break in.

 Do not carry keys in your purse.  If your purse is stolen with your keys, thieves may have access to your home;

Beware of persons causing a fuss or diverting your attention: pick-pocket teams often create a diversion (a skirmish or verbal altercation) to distract potential victims. If you are in a public place and witness a dispute, consider it might be a set-up for pick-pockets in the crowd. Pick-pocket teams will also work in very cramped quarters, such as buses and subway cars;

 Avoid placing your wallet in your back pocket or backpack as this makes it easier for pick-pockets to steal. A professional thief will be in and out of your backpack or pocketbook and you’ll never feel a thing!

 If possible, avoid carrying large sums of cash or checks. Instead, use credit cards for purchases, and make sure to contact your credit card company immediately if your card is misplaced or stolen;

 When at the gym, use a sturdy lock on your locker: do not leave it opened. Health clubs are among the most frequent theft targets in NYC.

Use a sturdy lock when securing your bicycle or scooter outside. The NYPD can etch a VIN number on your bicycle for ID purposes. Remember that bikes are classified as vehicles in NYC and can be removed legally by the Parks Dept. if chained to a tree. Likewise, it’s illegal to park your scooter or motorcycle on the sidewalk: it will be towed and you may not get it back!

 Identity theft is the fastest growing crime in America, so be sure to tear up or shred your discarded financial papers and mail. Thieves often browse through trash, looking for bank solicitations, credit card receipts, and other materials to steal your name or use your credit. Invest in a shredder: it’s your best weapon. Do not carelessly leave or toss bank or credit card receipts. Do not throw your personal mail in a public garbage can: it’s a violation of sanitation law and a gift to thieves.

If you are victimized, do not be embarrassed to report it: Visit the 20th Precinct, 120 West 82 Street, between Columbus and Amsterdam Avenues.
