The activist Yahoo shareholder who uncovered an error in Yahoo Chief Executive Officer Scott Thompson’s credentials is calling for the company to dismiss the CEO and appoint an interim leader, reports the New York Post.

Daniel Loeb, the CEO of investor Third Point, sent a letter to the Yahoo board suggesting that Chief Financial Officer Timothy Morse or Ross Levinsohn, Yahoo’s head of global media, be considered as an interim replacement.

As previously reported, Thompson listed a bachelor’s degree in computer science from Stonehill College, although the institution didn’t offer the degree until four years after he graduated. Yahoo has formed a special three-person committee to investigate his academic credentials and why they were misrepresented in regulatory filings.
