On that Saturday, the resident received a phone call from someone posing as a detective. The resident was suspicious and contacted the police while still speaking with the scammer. It soon became clear it was a phone scam, allowing officers to arrest a 17-year-old suspect later at the residence in Capelle aan den IJssel. The police are handling the case and conducting an investigation. 

Do not let them in, no matter what they claim
Phone scams are excuses criminals use to try to defraud people. The scammers often appear trustworthy. They call, come to the door, or approach people on the street with a convincing story. They then ask questions about money and other valuable possessions. A real police officer or bank employee will never call or come to your door to collect jewelry, money, or a bank card.

The police advise always calling 112 if you receive a call from a (suspected) scammer or if a (suspected) scammer is at your door. The police can then verify whether it is a phone scam. This increases the chance of catching them in the act. Additionally, it helps the police to monitor this type of crime, and through such reports, as in this case, multiple suspects directing the fake officers on the street can also be arrested.
