Maybe a bit unexpected however not really. Sarissa Resources and individuals associated with Sarissa could well be a target of Regulators and other Authorities.
Not only are there the individuals and issues that JPValas brought up that may interest Authorities but the issues outlined in the Lawsuit against (President / Director) Dan Byrnes filed by the US Government; Former President / Director Ben Ward Directorship and involvement in a Canadian Cannabis Operation; Scott Keevils financial involvement with the same Cannabis Company. Cannabis may be thought of liberally by Canada but the US Government still views it as an Illegal drug with continuing law enforcement involvement.
When you combine the Company's history with last years pump and dump (October 2014 PP well below then market price arranged by Daniel Byrnes, Short hold period on PP - 4 months 1 day, flurry of PR s issued by Company under then new President Daniel Byrnes name, cessation of all Company communication in April 2015) along with other questionable behaviours you have a recipe that will attract the Regulators interest.
