Police today said a 28-year-old woman insulted the victim and ripped the veil of the burqa from her head.
The attacker then followed the 54-year-old victim out of the store and continued shouting anti-foreigner abuse at her before being detained by police.
Police gave no more details of the incident.
Last year the German Parliament approved a government proposal to ban the wearing of all veils that fully cover the face by public employees in schools, courts and other institutions.
