Four persons, one of them a juvenile, allegedly murdered a small-time cloth vendor after taking him to be a member of a rival gang, police said.
The incident took place on August 11 when the four accused allegedly stabbed to death 28-year-old Amit in the Dakshinpuri area of south-east Delhi.
"Gaurav, Nitin and Mahesh along with a juvenile were involved in the crime. All four have been arrested," said Deputy Commissioner of Police (South East), P Karunakaran.
According to police, there was intense rivalry between two groups of anti-social elements operating in the area and they would be involved in frequent clashes.
