Former Jharkhand chief minister Madhu Koda surrendered in a Ranchi court on Friday and was sent to 14 days' judicial custody. He was on three weeks provisional bail that ended a day before.
"I was granted provisional bail to look after my ailing mother. My mother needs my support. She is unwell and hospitalised," Koda told reporters before surrendering.
Koda has been in jail since November 2009 on several graft cases.
Investigation of the cases is being carried out by the Income Tax department, the Central Bureau of Investigation, the Enforcement Directorate and the state vigilance department. Apart from graft cases, Koda is also at the centre of a Rs 2,500 crore money laundering scam.
