Authorities say Morgan sought to exert control over Lee even though he didn’t have authority to act on Lee’s behalf.

Attorney Alex Kessel has said Morgan has never abused or taken advantage of Lee. Kessel said Saturday that he had been in contact with prosecutors to arrange for Morgan to surrender next week but he was arrested anyway.

Before his death, Lee was granted a temporary restraining order against Morgan to avoid contact.

Lee was the creator of many legendary Marvel superheroes such as Spider-Man, Iron Man and the X-Men. He died in November of last year at the age of 95.
