The incident took place around 1:30 PM in C-3 block in Nand Nagri area.
"It all started when two youths, who were flying kites in a park, had an argument after one of them allegedly threatened another belonging to a different community and demanded money to let him fly kite in the park," said a police official.
The minor argument soon snowballed into a clash with more people from the two communities joining in.
Today being a holiday, a large crowd gathered within no time. Someone called police and even policemen who reached the spot first faced some resistance.
