Lets say there is a numpy array

```
arr = np.array([[1, 4, 2, 4, 7],
                [6, 7, 9, 2, 8]])

```

I want to split this array in two, but at a specific index i.e [1][1]
So it would be split from the number 7 in the second row onwards and the new arrays would be

```
arr1= [1, 4, 2, 4, 7],
      [6, 7]
arr2 = [9, 2, 8]

```

Is this at all possible using numpy?
