A group of protesters gathered outside the mosque on Saturday afternoon with union flags and a large banner saying “no more mosques.”
The protest spilled onto Whitechapel Road and scuffles took place between protesters and worshippers.

A Metropolitan Police spokesman said: “Police were called following reports of a protest outside the East London Mosque on Whitechapel Road.
“Officers attended and spoke with the group. A short time later, a counter-protest commenced.
“Two men were subsequently arrested.”
East London Mosque tweeted saying the arrests were for “provoking and attacking members of the community.”
Britain First claimed on its website that it “held a peaceful, silent protest outside the notorious East London Mosque.”
“Within 20 minutes, around 150 aggressive Muslims assembled who promptly attacked our activists, stealing expensive camera equipment, and inflicting violence on our activists.”
