India, Aug. 29 -- Union home minister Amit Shah on Friday asked Rahul Gandhi to apologise for the alleged abusive language used against Prime Minister Narendra Modi and his late mother during Congress's 'Voter Adhikar Yatra' in Bihar's Darbhanga. Amit Shah's sharp attack comes even as the Bihar Police arrested the accused earlier on Friday.

"Rahul Gandhi should apologise for abuses hurled at the prime minister, his late mother," said Amit Shah in Guwahati, adding that the Congress leader's politics "touched the lowest level with his 'Ghuspetiya Bachao Yatra' in Bihar".

The incident has snowballed into a massive political controversy in poll-bound Bihar as the Bharatiya Janata Party and Congress workers clashed in Patna on Friday.
