Tamil actor-politician Khusbhu's house was attacked this afternoon by a group of about 20 men who hurled stones at her windows.
The police says the vandals belong to Khushbu's party, the DMK, and that the attack was in retaliation for a recent interview she gave; but the party has denied the charges.
Khushbu has reportedly upset a section of the party by her comments on how the DMK will pick its next chief. She reportedly told a Tamil magazine recently that after current president M Karunanidhi steps down, his son, MK Stalin, will be promoted to the top post after the DMK's general council approves of the change.
Mr Stalin and his older brother, MK Alagiri, are both competing to be DMK president. Their rival camps frequently exchange sharp remarks in public.
Their father suggested last month at a party function that he has picked Mr Stalin as his successor, prompting a terse rebuttal from his other son, who said, "The DMK is not a mutt
(religious sect) where successors are appointed."
