Mystery door

I've seen this door many times before, but today, stuck in traffic on my way into  Nottm i had the chance to get a shot.
After waking up to the very sad news in Nottm this morning, i was reluctant to carry on with the day I had planned.
However, seeing the very heavy police presence on tv, i decided to carry on regardless. 
Town was quieter than usual, not sure if down to the weather or todays circumstances.
Above all, my heart goes out to the family and friends of the victim's.
