Facebook crime has increased substantially over the past five years according to police reports. Crimes linked to Facebook have risen over 500% in the UK, with over 100,000 cases reported in the last five years. Police are using Facebook to help solve crimes by posting photos of suspects to gather public tips. However, the large number of Facebook users has also enabled more opportunities for criminal activity like cyberbullying, stalking, and fraud. Authorities warn people to be cautious about sharing private information online.
