Harbhajan Singh slaps Sreesanth after an IPL game. Or did he? Ducking Beamers has the story about hierarchy just right:

...More than one observer has noted the strict hierarchy that exists in South Asian teams, with junior players required to slavishly do the seniors’ bidding. I think John Wright wrote about how amazed he was to find players scurrying around carrying tea and biscuits as the legends lazed about during team meetings.

There’s something about that here: Sreesanth, who is still in his early 20s, just got chided in public, and rather than being outright angry about it, he falls into himself, distraught and emotional. It reminds me of my days in all-boy Catholic schools in Bombay, when just a hint of reproach from older students would do enough to ruin your week...

Homer has a less than sympathetic take on Sreesanth. As far as Harbhajan goes, this is not just an IPL matter but also directly a BCCI problem, hence the show cause notice.

And see this article for a history of his on-field misbehaviour, which ends: 

Symonds accused Harbhajan of racially abusing him during the infamous Sydney Test but an ICC investigation conducted after the BCCI threatened to pullout from the tour found him not guilty.

The Australian team did not take too kindly to the verdict and opener Matthew Hayden even went on to describe Harbhajan an "obnoxious little weed", a comment for which he later apologised.

The whole nation rallied behind Harbbhajan during the furore and the same man now finds himself at the centre of yet another ugly episode but this time against a teammate.
