catch red-handed: to find or discover someone while they are doing something wrong, with clear proof

Definition

To catch red-handed means to catch someone in the act of doing something wrong.

If you catch someone red-handed, you discover them while they are actually doing something illegal, dishonest, or forbidden. The evidence is immediate and obvious, so they cannot easily deny it. It is often used in everyday situations as well as in crime-related contexts.

  • They were caught red-handed trying to break into the garage.
