If you press charges against someone, and if in the process the police discover that you have a warrant for your arrest that remains outstanding, they have a duty to arrest you. Whether they will necessarily check you out to see if you have a warrant for your arrest is another matter. That does not always happen as a matter of course. However, there is always the risk that they will do so and you would typically be arrested on the spot.
Added; In most professionally administered law enforcement agencies it is standard practice to "run" the names of EVERYONE involved in a case through a criminal history computer check.
Yes.
Kind of unlikely. If/When they run your name into the sytem to check on you, the warrant will probably show up, and you'll be arrested.
You can be arrested and detained without a warrant. A criminal attorney can give you some help, and if you have been arrested, you should consult one immediately.
Yes.
When the person named in the warrant is arrested, he will be held without bail.
Yes i you have a warrant, but not technically.
Yes they can search it
A warrant is an order for an arrest issued by the court. But many arrests do not need a warrant. If you punch someone in the face, and police are called, you will be arrested without a warrant, and one will not be needed. If say, you failed to show up in court, then a warrant for your arrest will be issued, to alert all officers that you should be arrested on sight. So the warrant itself is not the thing 'allowing' you to be arrested.
If an arrest warrant exists then you are subject to arrest at any time or place. Being at work will not prevent your being taken away in handcuffs.
Being arrested on capias means being taken into custody based on a court-issued warrant or order, often due to failure to appear in court or comply with court directives. It is separate from being arrested by law enforcement for a criminal offense.
Unless the arrest warrant specifically states that the issuing agency will extradite then you can not be arrested for it.
If they were arrested as a result of a search warrant being executed - it all depends on what the search warrant was for (what crime/offense) and whether the evidence being searched for was found (I'm assuming it was).
