He could be in jail until he finishes his sentence for the assault.
The fact that he missed/skipped tells the judge that he cannot be trusted to return for court. Many judges will refuse to release a prisoner who has had to be arrested on a warrant because it's likely that he will fail to appear again.
Failing to appear is not smart. Judges get mad too.
No warrant is ever necessary. Any armed assault is a felony offense for which only probable cause is necessary to effect an arrest. So-called 'Simple Assault' in most(all?) jurisdictions is a "probable cause misdemeanor" and, unlike the vast majority of other misdemeanor offenses (which must be committed in the officers presence for an arrest to be made), you can be arrested for it based on probable cause alone.
If there's been a warrant drafted for your arrest, yes.
He was arrested based on a Swedish arrest warrant charging him with sexual assault.
I'm not aware of any states extraditing for a misdemeanor, but the misdemeanor warrant will remain active until the individual is arrested, therefore, if you go back to the state where there is a warrant, you are subject to being arrested.
no
No. An arrest warrant is valid until it is served or cancelled by the court.
A warrant is a judicial order for an arrest. If the warrant was still valid, the law enforcement officer has no choice but to make an arrest.
Yes
Unless the arrest warrant specifically states that the issuing agency will extradite then you can not be arrested for it.
If NE enters the warrant into the interstate NCIC system and indicates they will extradite on it it, yes, WY will arrest you and hold you.
Yes, you can and will be arrested.
if the warrant is for your arrest then yes you would be arrested
