After the imminent family freakout I managed to capture this beast. I am curious what species it is. It's more than 6cm long which is the second largest I've ever seen 'in the wild' (not in a terrarium). The largest which was about 10cm I met in a toilet while on holidays in '11 and I've only got a very hazy (night time with cell phone) photo of it.
It was under the TV shelf if that helps. Maybe it's connected to media.
