For example , in Iran ,left-wing parties. when one of your members become known to people ,especially police ,you can be sure to assign a work to him or here anymore. he or she is not necessarily a person with bad fame . perhaps he is even for them a hero .

I assume you meant cannot be sure to assign work to him anymore?

If so it kind of sounds like "Burned" or "Compromised." These meanings come from espionage terms. Not sure if they're actually used by real spies, but they were used a lot in spy novels and movies.

It means that the person involved is no long useful against a particular group or in a location because they are now well known by them.

Burned tends to mean that the action that made them known was intentional and controlled. For example an undercover police officer will have to become known if he arrests a bunch of criminals. (see the example below)

Compromised tends to indicate it wasn't intentional and also indicates the person might be in immediate danger. For example the police might find out the identity of one of your members, and the member works at the police station feeding information to other members. Well he's suddenly in immense danger now.

A full example: In the U.S. a police officer might pretend to be a drug dealer in order to infiltrate a drug organization. Once the officer gathers enough evidence he'll call in other officers and they'll arrest the leaders of the organization. Afterwards, the police officer gets a medal and ends up all over the news. He's now "burned" as an undercover police officer since anyone that saw that news broadcast will instantly know he's a police officer.

Is that closer to what you meant?
