A Nanny who was paid £3.60 an hour shook a 10-month old baby boy to death when she "snapped" minutes after his mother left for work, a court heard.

Viktoria Tautz, 34, allegedly killed Joshua Paul by using "excessive and dangerous" force when she lost her temper while looking after him at his north London home.

Joshua suffered bleeding in the brain and bruising to the spinal cord and died in his parent's arms at Great Ormond Street Hospital two days later.

Tautz, a Hungarian student who was employed through an agency, told police that they had played a game of "horsey" on her knee that morning but he did not fall or show any pain.
