Two mobile phone towers of a private company were blown up in the Gaya district in Bihar on Wednesday night, where two election rallies were to be addressed by Narendra Modi, the prime ministerial candidate of Bharatiya Janata Party (BJP), according to media reports. 

The towers were situated in the Manjhauli and Dumaria Bazar villages in the district. The Maoists have called for a shutdown in the Maoist-hit districts of central Bihar to protest the killing of 10 of their associates in the Chhatra area recently, said Superintendent of Police Nishant Tewari on 27 March. 

Bihar Director General of Police (DGP) Abhayanand said the Maoists have used powerful bombs to blow up the cellphone towers. Modi's two election rallies were scheduled to be held in the same area, he stated.  

"We have anticipated all types of threats from the Maoists and terrorists. Security arrangements are being made accordingly," a PTI report quoted Abhayanand as saying. 

This is not the first time that bomb blasts preceeded Modi's public rallies in Bihar. Five persons were killed and more than 60 were injured in a Patna rally back in October. It can be recalled that former Prime Minister Rajiv Gandhi was killed by an LTTE activist at an election rally in Sriperumbudur, near Chennai in May 1991.
