Bhopal, May 23 : At least four people were injured after two groups indulged in violence and pelted stones at each other in Madhya Pradesh's Ratlam district. The incident took place due to the playing of DJ at a marriage procession to which the other group objected which resulted in violence, local police said on Monday. As per the police, on Sunday night, a Muslim family was carrying out a ritual process after marriage. Some of them were dancing to the tune of the DJ. As the procession passed through a temple at Kothdi village, a group of people from the Hindu community objected to the songs being played. This resulted in an exchange of heated arguments between the two communities, which soon turned violent and stones were pelted at each other. Police said at least four people were injured due to stone pelting and they have been admitted to a government hospital in the district. After getting information, a team of local police reached the spot and tried to bring the situation under control. Additional police force from adjoining police stations was also brought in to control the situation, police said. In the meantime, district SP and SDM (Sub-Divisional Magistrate) reached the spot.
