Seems like the guy who lived there is moving and came back today to bring his gas stove to his new home.
Funny bit...
The guy who left his gas open... was one of the firemen.
PS: If a thing like this is considered serious enough to bring in two police cars and a fire truck... would you then not think it's important enough to I don't know, press a few doorbells and let people know what's going on?
I only found out after I heard someone talk on the megaphone and looked outside to see what was going on. It seems they didn't think the situation was dangerous enough to warn people to get out...
(what can I say, my first question was to ask if things were dangerous enough for me to go get my cat out of the building and take her out to safety.)
