At work now, like two previous nights (after now four free nights).
Otherwise it has been quiet except as I was leaving for nightrounds about 45 minutes ago and stepped out from frontdoor of the building where our office is I was stopped by two policemen.
They asked who I was and let me go. They checked the list on the wall of people living in the house and were acting bit nervous. I was checking what they were doing while dusting snow off from our work car and de-icing the windshield.
No idea who they were after.

When I returned the police were gone but the lights of the building (more precisely the basement floor ones) auto-switched on without anyone being visible or heard so there might be someone hiding there but I'm safely in the office now behind locked doors.
