Did Kahar Hassan do something naughty for the PAP to turn their backs on him?

From potential PAP candidate in Aljunied GRC to a political nobody. Isn't it curious how the PAP suddenly decided to replace a PAP Branch Chairman who has walked the Kaki Bukit ground for the past 16 months without any explanation or reasons given for the decision? 

The poor chap wasn't even asked to help out with the new team, told about his next posting, or even invited to the launch of the party's manifesto!

It certainly doesn't help that Lim Boon Heng 'clarified' that the PAP's decision was "not because he's done anything criminal or there's a scandal". 

Oops, did someone just make a Fruedian slip? Maybe someone received too much warmth, love (and hugs)! from his residents huh? :P
