Pat McDonagh, chairman of e-learning group Thirdforce has bought a 25% stake in the group, which he wants to take over.

Pat McDonagh and Thirdforce CEO Brendan Sullivan launched an offer for the company at eight cent a share earlier this week.

They also offered investors an alternative of one share in their special purpose vehicle, LearnVantage, for one Thirdforce share.
