A former business manager of Stan Lee was arrested Saturday on elder abuse charges involving the late comic book legend.

Keya Morgan was taken into custody in Arizona on an outstanding arrest warrant after being charged by Los Angeles County prosecutors earlier this month.

Morgan faces felony charges including theft, embezzlement, forgery or fraud against an elder adult, and false imprisonment of an elder adult. A misdemeanour count also alleges elder abuse.

Authorities say Morgan sought to capitalise on the Marvel Comic mastermind's wealth and exert influence over Lee even though he had no authority to act on his behalf.
