What can I do if ICE was looking for me?

I am on 5 year probation of a party to crime theft Felony, so far I almost done with the first year, last week I had 2 guys came to work and my house looking for me saying that they were from my probation office, I was not home so I called my PO first thing in the morning next day asking to see what was going on, but he said that apparently ICE was looking for me. It has been a week and I have not heard anything back..I am very worried I really do not know what is going on. I have my children and my husband here. Please give some advice.
