Sorry about this mate its really annoying to see.
They have smashed the window in that place by jamming a screw driver in as its make an almost silent smash, alarm probably went bonkers though?
In summer last year, I got out of bed and walked down stairs to find muddy foot prints everywhere and it looked like a scene from Paranormal Activity as everything was open.
Not one thing was stolen, they were looking for cars keys but fortunately I take them to bed with me.
