Malinga, who was approached by the media for comments over the payment dispute which had erupted between the SLC and 23 national players recently, behaved in a rude manner with the media personnel outside the SLC headquarters here.
He was seen on a local television reacting in an unwarranted fashion.
A Board official said that Malinga's unruly behaviour will be investigated and the inquiry report would be forwarded to the Executive Committee of SLC.
