Thank you for your inquiry.
The answer is, it depends. If this was a simple touching case, it will likely be charged as a low level crime, and extradition is unlikely. If the DA can secure a felony indictment, he'll certainly try to bring you before the court to face the charges.
First, he lied. You can't be arrested for refusing a polygraph.
Second, if you have an outstanding felony warrant, it means that they have charged you with a felony.
Typically, if you have an active warrant, you can be arrested in your own state, and held for possible extradition by the charging state. A DA will typically seek extradition if he has charged a person with a serious crime.
If you find out the charge, I can offer you better advice. Without knowing the charge it's difficult for me to opine.
