I was accused of stealing from a person I used to be friends, He extorted money from me said they charges will be dropped, but haven’t what can I do?

First, the person who is the 'victim' of a crime does not have the power to 'drop the charges'. Once a crime is reported and police investigate it and decide to charge a person, the charges typically go forward. Second, if there is a warrant for your arrest, the best thing to do is to find out what the bond amount is, as set on the warrant. Then turn yourself in, prepared to pay the bond so you can be 'booked and released', as opposed to having to wait to see a judge. That way you can control when you are taken into custody so it has the least impact on you and your child.  Third, consult, in person, with a lawyer - or once the charges are formally filed in court (after you are arrested on the warrant) apply for the pubnlic defender if you think you qualify financially - and tell them the full story, including proving repayment of the 'victim'.  The case likely will be able to be resolved fairly easily (depending ont he specific facts).
