Violence caused due to Sports

Most of my friends like to play cricket as cricket is the most popular sport in India .I live in India but

foot ball is my favourite sport. Sports causes children's body to grow faster. Sports also help in muscle growth. It helps to reduce osteoporosis or calcium loss from bone. But it is also seen that it causes violence among children. It's also seen when one team wins in a game against the other the other team uses physical violence against the members of winer team . Last year this physical violence caused serious injury to a Student of Don Bosco High School when a student from the winner team was pushed from back and he fell down stairs breaking his leg. This type of incedent should be stopped by either banning sports in schools or by imposing serious punishment against the bulies.
