Police's job is to stop the Illegal happenings in their country and if you are an illegal imigrant, (even if you havent happened) and if they found out, yes they would definetly arrest you!
There is no such thing as an illegal argument so the illegal police will not arrest you.
no
Because a lot of drug addicts sell drugs, which is illegal. Therefore, police officers have to find them and arrest them.
If whatever you're doing is illegal in your locality, yes. If it isn't illegal, no.
That would be illegal. They have to follow due process.
No. And them saying they will is an illegal debt collection practice. What they can do is file a complaint with the police, and if the police believe you committed a crime the police can either do a probable cause arrest or ask a judge to sign an arrest warrant. The company does not get arrest warrants.
any body inform to local police about illegal immigration if have only name and mobile numbers
It sounds like you're asking an opinion question. In my opinion, yes. If a person is caught with illegal drugs, yes, a police officer should arrest the person.
Police may arrest anyone who has committed a crime, whether they are citizens or immigrants. Immigrants may have additional restrictions or requirements beyond those of normal citizens, depending on the country. In some countries, the responsibilities for enforcing different titles of the law are split among different law enforcement agencies, while other countries have a single police force. In countries where the enforcement responsibility is separated, a law enforcement agency may contact the proper enforcing agency if it becomes apparent that a crime has been committed, which a different agency enforces. For example, in the United States, aliens present in the country without the permission of the country (e.g. illegal aliens, invaders, spies) might be detained by the local police, who would then notify the enforcing agency (e.g. illegal aliens -> ICE, invaders -> army, spies -> FBI).
Officially no. But it is still considered a horrible sign and if you begin wearing it the police will immediately arrest you.
Any duly consitituted law enforcement officer possessing the power of arrest may arrest a judge. An exception may be if the judge is actually on the bench and presiding at an in-session court hearing. Then the arrest may have to wait until his/her court is adjourned for the day.
A person is "under arrest" when a police officer charges them with a crime and chooses to take them to the police station to be processed for it. For example, if someone commits a crime, they are technically under arrest when a police officer witnesses the crime or has a warrant for the arrest and tells the criminal "You are under arrest." Typical procedure after this is to put handcuffs on the criminal and read them their Miranda rights (you have the right to remain silent etc). Handcuffs alone do not mean arrest, but i'm pretty sure its illegal for a police officer to handcuff someone without grounds to arrest them. As a side note, the person doing the arrest does not have to be a sworn in police officer. In Citizen's arrest cases, anyone with arresting powers like a bounty hunter can also place someone under arrest.
