Not sure if this has been posted already, but Innofix gave the following comment on the 21st:-
"The board also expressed its disappointment with the performance of the
investment in AeroBox PLC during the period. Share value came under downward
pressure following lower than expected results and an additional cash call.
As a result Innobox decided to sell most of its remaining shares which
resulted in a 16,642 stg loss on disposal."
Which would suggest they had prior knowledge of the cash call.
That's either a pretty dumb thing to write or a rather large assumption.
