The object on the photo looks like pieces of industrial slag I have seen. So 
that would be my first interpretation of it, rather than space debris, unless 
something in the composition/morphology suggests otherwise and clearly connects 
it to space debris.

Note that each year I get several reports (as potential "meteorites") of objects 
that did damage, including objects that went through windows. Invariably it is 
accompanied by "reasons" (as in the BAA article) why it/the damage "cannot" have 
a terrestrial origin. Over the past 20 years none of it however was a genuine 
meteorite or space debris. So be careful there.
