Detective
In short
A detective is a trained investigator who gathers evidence and information to solve crimes. They work for police forces or private agencies to identify and arrest criminals.
In plain words
Detectives look for clues to figure out what happened during a crime. They interview people, search for physical proof, and check records. Their goal is to find the person responsible so they can face justice in court.
A simple example
A detective visits a shop where a theft occurred to interview the staff and check the CCTV footage. They then match fingerprints found at the scene to a suspect in their database.
Why it matters
Without detectives, many crimes would remain unsolved because there would be no one to piece together complex clues. They ensure that evidence is collected properly so that criminals can be legally convicted.
Easy to mix up
Do not confuse a detective with a constable; a constable usually performs general patrol duties, while a detective focuses on specific investigations.
