After i found my husband is married before married to me.he went to the police and falsely accused so he can be granted a 10 green card .he lied to me

I'm not sure what you mean by "he went to the police and falsely accused so he can be granted a 10 green card."  Do you mean that you petitioned him for a green card based on your marriage to him?   If was married before and did not divorce wife #1 and married you, then your marriage is void ab initio (meaning that your marriage is void from the beginning).  Therefore, his green card should be taken away from him.  You need to let USCIS know.
