On public transportation such as subways or buses, pickpockets may use some common tricks to steal passengers' valuables. Here are some common methods: 1. **Distraction**: Pickpockets may use crowded crowds, create small chaos or pretend to fall to distract their targets while their accomplices steal. 2. **Stalking**: Pickpockets may stick close to their targets when getting on or off the train or walking around the train, using physical contact to cover up their theft. 3. **Using a coat or bag**: Pickpockets may use items such as coats, school bags or newspapers to cover their hands so that they are not easily seen. 4. **Pretending to be a passenger**: Thieves sometimes disguise themselves as ordinary passengers, pretending to be on the phone, reading a book or playing with their mobile phones, and take the opportunity to get close to passengers to steal. 5. **Quick snatch**: Pickpockets may quickly snatch items from passengers' hands or pockets when the doors are about to close, then get off the train and escape. 6. **Targeting specific items**: Some pickpockets specifically look for conspicuous items such as mobile phones and wallets placed in coat pockets, back pockets of pants or open bags. 7. **Gangs**: A group of pickpockets may work together, with one person responsible for distraction, another for theft, and a third person who may run away. To prevent these tactics, passengers can take some precautions, such as placing personal items in front pockets, carrying backpacks in front of the body, and being vigilant, especially during crowded times.
