Rio's facial recognition system led police to take an innocent woman to a station

In progressPress reporting

Problem

Police used street cameras to identify people wanted by the authorities.

Approach

A camera in Copacabana flagged a woman as a wanted person. Officers took her to a police station because she lacked identification, then released her after relatives established her identity. The person on the watchlist was already imprisoned, and police said they would request database improvements.

Results

No published figures

Takeaway

The incident involved both a mistaken match and an outdated watchlist. Relatives had to establish the woman's identity before she was released.
