K Shanti, wife of Hindraf chairperson P Waythamoorthy, voluntarily spent the night at the Putrajaya district police headquarters in protest of the detention of her 10 friends and relatives.

"I told them that I was not leaving without my relatives and friends, as a protest. I only left at about 7.30am today to go to court," said Shanti, who looked exhausted from lack of sleep.
