Be aware of pickpockets, homeless individuals, scam artists, radical social activists, and any areas of unlawfulness.
Unfortunately, Europe is suffering from higher crime rates due to refugee influx. Many homeless individuals will pickpocket or scam others, especially the young or vulnerable. Instruct your child to stay in their group, avoid large crowds, and keep important belongings like their money or wallets in a bag that zips or fastens shut. As an extra precaution, suggest your child leave all valuables at home, or in a separate compartment.
Public transportation, restaurants, nightclubs, and outdoor areas such as markets are common areas for pickpockets–so instruct your child to be especially cautious when in areas of heavy traffic such as these.
