In a statement, NAPA spokesperson Satnam Singh Chahal said the bar owner expressed ignorance of the significance of these portraits and said they were not aware that these portraits were of Sikh Gurus.
The bar is owned by Committed Inc, which owns eight restaurants in southern California, including two branches of the Swingers' Diner, Bar Lubitsch, Jones Hollywood, El Carmen, and the Roger Room.
In a letter to Congressman John Germandy, NAPA said displaying full-size portraits of the Sikh Gurus in a bar where alcohol is being served was hurting religious sentiments of the Sikh community.
"Bar manager Hallyeluyah assured me that before the end of the day, he would remove all portraits of Sikh Gurus from their establishment," Chahal said in his letter, adding that the portraits had not been removed till Wednesday.
The association also wrote a letter to the local police in this regard.
