Removing character from array using strchr, does not return right value in plain C

Question

I am trying to remove first semicolon from a character arrary whose value is:

Input:
; Test: 876033074, 808989746, 825766962, ; Test1: 825766962,

Code:

 char *cleaned = cleanResult(result);
            printf("Returned BY CLEAN: %s\n",cleaned);



    char *cleanResult(char *in)
    {   
        printf("Cleaning this: %s\n",in);

        char *firstOccur = strchr(in,';');
        printf("CLEAN To Remove: %s\n",firstOccur);
        char *restOfArray = firstOccur + 2;
        printf("CLEAN To Remove: %s\n",restOfArray); //Correct Value Printed here

        char *toRemove;
        while ((toRemove = strstr(restOfArray + 2,", ;"))!=NULL) 
        {
            printf("To Remove: %s\n",toRemove);
            memmove (toRemove, toRemove + 2, strlen(toRemove + 2));
            printf("Removed: %s\n",toRemove); //Correct Value Printed
        }

        return in;
    }

Output (first semicolon still there):
; Test: 876033074, 808989746, 825766962; Test1: 825766962;
