Laws of Cricket 1980 Code - Law 41
1. Fielding the Ball
The fieldsman may stop the ball with any part of his person, but if he wilfully stops it otherwise, 5 runs shall be added to the run or runs already scored; if no run has been scored 5 penalty runs shall be awarded. The run in progress shall count provided that the batsmen have crossed at the instant of the act. If the ball has been struck, the penalty shall be added to the score of the striker, but otherwise to the score of byes, leg-byes, no balls or wides as the case may be.
2. Limitation of On-Side Fieldsmen
The number of on-side fieldsmen behind the popping crease at the instant of the bowler's delivery shall not exceed two. In the event of infringement by the fielding side the umpire at the striker's end shall call and signal "no ball" at the instant of delivery or as soon as possible thereafter.
3. Position of Fieldsmen
Whilst the ball is in play and until the ball has made contact with the bat or the striker's person or has passed his bat, no fieldsman, other than the bowler, may stand on or have any part of his person extended over the pitch (measuring 22 yards/20.12 m x 10 ft/3.05 m). In the event of a fieldsman contravening this Law, the umpire at the bowler's end shall call and signal "no ball" at the instant of delivery or as soon as possible thereafter. See Law 40.1 (Position of Wicket-Keeper).
4. Fieldsman's Protective Helmets
Protective helmets, when not in use by members of the fielding side, shall only be placed, if above the surface, on the ground behind the wicket-keeper. In the event of the ball, when in play, striking a helmet whilst in this position, five penalty runs shall be awarded, as laid down in Law 41.1 and Note (a).
Note
1. Batsmen Changing Ends
The 5 runs referred to in 1 above are a penalty and the batsmen do not change ends solely by reason of this penalty.
