WTF is this Insect??

[lugh]

Found upstairs, may have fallen out of Velux windows. Dead. 
Found another once outdoors under dead leaves, weeds and gravel. It was alive and crawled around very slowly. Eventually killed by the dog. 
These were the only two I ever found, never more than one at a time. 
About 1 and a half inches long. 
Please tell me this is not a cockroach or some colonising species.

Not a roach. It's a water beetle, some Dytiscus species. They fly and are attracted to lights, as well as shiny surfaces during the day.

Aquatic beetle probably drawn to lights at night. Harmless. Must reproduce in ponds/ water.

My relief is immeasurable. 
Now that you have pointed it out I do remember catching similar looking creatures in ponds as a kid. They were never that big though.
