NEW YORK (

TheStreet

) -- Activist investor Carl Icahn has snapped up an additional 3.3 million shares of

Motorola

(MOT)

over the past three sessions, according to a new filing with the

Securities and Exchange Commission

.

In a Form 4 disclosure after Tuesday's closing bell, Icahn disclosed the purchases of 678,500 shares at $7.51 each on Friday; 200,000 shares at $7.52 each on Monday; and a whopping 2.41 million shares at $7.51 each in Tuesday's session.

The transactions bring the total number of common shares controlled by Icahn -- who made the disclosure because he's already a 10% owner of Motorola's outstanding stock -- to more than 250.4 million.

Motorola shares finished Tuesday flat at $7.52, and the stock was moving slightly higher in afterhours action, rising 7 cents to $7.59. Year-to-date, the shares are down a little more than 3%; although they've seen a decent bounce overall since sinking to their 52-week low of $6.04 in late January.

As of June 30, Motorola had 2.37 billion outstanding common shares on a diluted basis. The latest buys bring Icahn's stake up to roughly 10.56% based on that figure.

Icahn made news earlier Tuesday as shares of

Lions Gate Entertainment

(MOT)

soared to a new 52-week high when he

lifted his acquisition bid

for the Canadian movie studio to $7.50 per share.
