Bowler breaks non-striker's wicket

Owner: A Newman

In a recent ECB Premier League match, the bowler broke the non-striker's wicket whilst delivering the ball. The umpire called and signaled "No ball" and the striker missed the ball which hit the stumps and went on to cross the boundary. Some of the spectators shouted that the ball was Dead and the umpire should signal accordingly, were they correct?

The spectators were wrong to suggest that the ball was dead. The delivery was correctly called as a No ball because the No Ball Law has been changed since the Stephen Finn incident against South Africa, it now reads - Law 21.6 Bowler breaking wicket in delivering ball
Either umpire shall call and signal No ball if, other than in an attempt to run out the non-striker under Law 41.16, the bowler breaks the wicket at any time after the ball comes into play and before he completes the stride after the delivery stride.

The umpire repeats the No ball signal to the scorers followed by the Bye signal and the Boundary 4 signal. One No ball extra plus 4 Byes are recorded because the ball did not hit the Striker's bat before breaking the wicket
