There is more wrangling over the attempt last month by Xerox Holdings to takeover HP.
According to Bloomberg News, a Xerox shareholder is suing activist investor Carl Icahn -- claiming Icahn bought 4 percent of HP knowing that Xerox was looking to pay a premium for HP stock.
The Xerox shareholder bringing the lawsuit is a pension fund for Miami firefighters.
Icahn also owns 10 percent of Xerox.
The HP board has rejected the Xerox takeover proposal.
