LHI's Arrest & Tax Returns First Family - Is This has a correlation?

KPK  is so powerful to heading PKS Chairman & Politician Case, Luthfi Hasan Ishaaq. LHI was suddenly arrested by KPK Team last week. He was allegedly receiving Rp 1 billion (US$103,000) in bribes from meat importer PT Indoguna Utama to secure a government contract.

Is this a transfer issue after Tax Return of First Family Hot News  blew up recently? I am individually not a 'fanboy' of PKS, but I see an unjustice on his arrest. Why did KPK arrested LHI on a quick time? On the contrary, KPK is slowly to arrest other suspect e.g. Anas Urbaningrum or any other politician. 

PKS is a nation assets. At least, I see it on now. PKS has many loyal cadres, and most of them relatively clean from case. The question is : Why did political opponents often bully PKS? Were they envious to PKS?  Let us see something happen beyond ---
