In this article I noticed an interesting anecdote that on March, 1947 the Hindu-Sikh areas of Peshawar were barricaded in their quarters and were being protected by the police.
If you look at this picture, the street that is in the foreground has a barricade guarded by the police.
From the original article:
"Relations between Muslims, Hindus and Sikhs was tense in the run-up to independence. By March 1947, a barbed-wire barricade separated the various religions' respective quarters of Peshawar, Pakistan, and the Sikh-Hindu minority observed a self-imposed curfew." (AP)
