German online lottery company Tipp24 has perhaps been too successful for its own good recently - reports are surfacing that an as yet unidentified company is attempting to buy up its stock.

A shareholder in Tipp 24, Earlybird Venture Capital, has notified the company that two organisations it was associated with have sold holdings constituting 13 percent to a single investor, and Tipp24 AG has confirmed in return that it has been advised by several other major shareholders that approaches had been made by a third party looking to buy up Tipp 24 shares.
