Hyderabad: Former Rajya Sabha MP Nandamuri Harikrishna, the son of N.T. Rama Rao and brother-in-law of Andhra Pradesh chief minister N. Chandrababu Naidu, died in a road accident in Telangana's Nalgonda district on Wednesday, police said.

The 62-year-old was going to Kavali in Nellore district of Andhra Pradesh to attend a wedding when his car rammed into the divider on the Nalgonda Highway and flipped on the other side, a police officer said.

"Harikrishna suffered severe head injury. We suspect internal bleeding too. However, the exact cause of the death is yet to be ascertained," duty medical officer of Kamineni Hospitals at Narkatpally, Ameer Khan, said.

Harikrishna had acted in several Telugu movies. His sons, Kalyanram and Taraka Rama Rao, popularly known as Junior NTR, are also famous Telugu stars.

Actor and politician N.T. Rama Rao served as chief minister of Andhra Pradesh for three terms. Harikrishna had been a minister in Chandrababu Naidu's cabinet in the late 1990s.

In 2014, Harikrishna's son Janakiram died in a road accident in undivided Nalgonda district. Vice-President M. Venkaiah Naidu said he was saddened by Harikrishna's death.

"As a popular actor he has entertained the Telugu audience. As a parliamentarian, he was very upright and expressed his opinions frankly. My condolences to his family, well wishers and followers at this time of grief," he tweeted.

Telangana chief minister K. Chandrashekhar Rao also expressed his condolences, an official release said. Rao recalled the services of Harikrishna in the fields of politics and cinema. PTI
