New EastEnders arrival Carl White (Daniel Coonan) will waste no time in threatening an Albert Square resident next week.
Warning: spoiler alert!
Carl is the ex-boyfriend of Kirsty Branning (Kierston Wareing) and a former cellmate of the late Derek Branning (Jamie Foreman).
He has come to Albert Square in search of Derek's missing £10,000, which he feels belongs to him.
It does not take Carl long to discover that Ian Beale (Adam Woodyatt) stole the cash in order to set up his new restaurant.
He then sets off to find Ian to explain to him the error of his ways.
The scenes will air on BBC One and RTÉ One on Thursday June 20.
