Yes you can. It happens every day. Ask anyone that was drunk and woke up in jail.
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.
The say "Don't move, put your hands up, and you're under arrest" if they are under arrest.
Arrest
Ankle bracelets or monitors are used to ensure that someone under house arrest remains within a certain range of the house. A signal is sent from the bracelet to a receiver that identifies the location of the person wearing it.
yes they do check you. Typically, as part of the arrest process, there is a search. However, depending upon the circumstances, the search may take place before the arrest, or you may be under arrest and the search can take place after.
Not in the UK.Added: Also the same in the US. Mere knowledge, on the part of the officer(s), that a warrant exists is sufficient cause to place the subject under arrest.
If the police have articulable probable cause to place you under arrest at the time they made the arrest, they may do so at any time and in any place. Insufficient information is given in the question about the issuance of the warrant, which may have been for an entirely different cause. If the police made an illegal arrest it is a defensible reason for the dropping of the charges.
No, it is a common noun. He is under house arrest. He violated his house arrest and went back to jail. It would be a proper noun if it was the actual name of a thing or place. She went to the House Arrest officer to arrange the release of her son.
you're under arrest
you're under arrest
you're under arrest
Not in the United States. First you have to be charged, which at that point, you obviously know you are being charged. Then, arraigned, where you plead and request bail, which at that point, they may put you under house arrest. But my point is, you have to be charged and then arraigned to be placed under house arrest, so there is no way you would not know of this.
