I recieved a call from this number today that said for me or my attorney of record to call back. It was pretty threatening but never said who it was that was calling or what it was about. I tried to call the number it gave back but no one answered.  Anyone know who this is?

I also got a call from them today regarding my husband. They told me that if he did not call today he would be arrested by the local police tomorrow.

Nobody's going to call your house and tell you that if someone in your household doesn't call back immediately that they'll be arrested tomorrow. If someone's going to be arrested, the police come and do it themselves without calling you first and giving you a day's warning to escape.
First hint that you're being scammed. I'd say, call back, say you're your husband, do NOT give any personal information beyond first and last name. See what they've got on you.

This is definitely a scam because it's illegal to threaten arrest over civil debt. Debt is handled in civil and not criminal court. The Better Business Bureau has released many alerts on this scam, google "bbb.org alert phony debt collector"  Scams mutate so read all the alerts to get a flavor of what they are. File complaints with the Internet Crime Complaint Center http://www.ic3.gov/complaint/default.aspx , the Federal Communications Commission http://esupport.fcc.gov/complaints.htm , the Federal Trade Commission https://www.ftccomplaintassistant.gov/ and your state AG, as appropriate.

Same thing wit me. The guy that couldnt speak good english left me a voicemail if i dont call him back about this legal document  i will be arrested.
