Kitchen explosion at Wells Terrace?

I heard a loud bang as I walked towards Finsbury Park this morning. I'm familiar with explosions and my heart sank. But walking along Wells Terrace all seemed normal although there was an acrid smell in the air. I cut up toward the theatre and down Morris Place to see several uniformed and plain clothes police seemingly in a confrontation with folk in the carwash, threatening to arrest them.  The police then started taping off the road into Wells Terrace as fire engines arrived. The latest is there was a possible gas bottle explosion at E. Mono Kebab shop at Wells Terrace. London Fire Brigade tweeting fire under control.

Luckily it appears no one was hurt.
