Law and disorder

Unprecedented levels of WTF-ery here in this news clip re the re-arrest of Irom Sharmila:

The police, however, is yet to press any charge against her and is reportedly seeking a relevant law to justify the arrest, according to a government official.

Is that how it works? You arrest someone first and figure out why later? (Actually, judging by recent events, that is exactly how it works.)

How on earth does a ‘government official’ even say that with a straight face?
