Deleting a reference

Is this valid? An acceptable practice?

typedef vector<int> intArray;

intArray& createArray()
{
    intArray *arr = new intArray(10000, 0);

    return(*arr);
}


int main(int argc, char *argv[])
{

    intArray& array = createArray();

    //..........

    delete &array;

    return 0;
}
