As per media reports, last evening , during Rehras sahib at Gurdwara Fatehgarh sahib, a reportedly insane man crossed over the golak and created a ruckus.
I thought this was a case of just an insane person, but one news article says he raised slogans of "Har Har Mahadev" and "Bharat Mata ki jai"
This is not the first time this had happened. A similar incident happened in 2008 when hindutva radicals were welcomed with siropas in Gurdwara Sri Fatehgarh sahib complex and raised similar slogans of "Har Har Mahadev"
