The pair, aged 14 and 15, are reported to have shouted abuse at the four people, who were wearing medical face masks, before confronting them.
The alleged incident, which occurred on March 17 in Vincent's Walk, Southampton, is believed to have been racially aggravated and linked to the Covid-19 pandemic.
Hampshire constabulary arrested the girls on suspicion of affray. They remain in custody.
The victims, three men and one woman, were all aged in their early 20s and did not suffer any lasting physical injuries.
