Two controversial politicians, including RJD MLA Surendra Prasad Yadav, have landed in trouble following their arrest order in criminal cases lodged with Shrikrishna Puri and Shashtrinagar police stations in Patna respectively.

Patna city (central) superintendent of police (SP) Chandan Kumar Kushwaha ordered the arrest of Surendra, sitting MLA from Belaganj in Gaya district, and Samajwadi Party (SP) state president Ramchandra Singh Yadav on Sunday.

"Preliminary investigations found the charges against the accused true," he added.

While Surendra has been booked on extortion and intimidation charges, the SP state president has been accused of accepting money in lieu of promising a party ticket to a social worker from Gaya. The charges against the SP's secretary-cum-media-in-charge Rajesh Singh were also found true.

The police officer said the SP state unit president and his secretary have been made accused under sections 406 (breach of trust), 420 (cheating), 120(b) (criminal conspiracy) of IPC and 136 of the Representation of Peoples Act, 1951.

"Since the sections are non-bailable, the arrest orders have been issued," Kushwaha explained. He said raids were conducted at the official residence of the Belaganj legislator in the capital on Sunday but he was not present. "The police also searched the house of Ramchandra Yadav in Patna but he could not be arrested," he said.

The investigating officers of the two cases have been directed to obtain the arrest warrant if the accused continued to evade arrest. "We are also in touch with our counterparts in Gaya to arrest the accused," he said.

Surendra allegedly threatened a Patna-based contractor, Arun Kumar, with dire consequences over phone on Saturday if he defied the former's diktat and bid for a Rs 7-crore contract in Gaya. The minor irrigation department had invited the bids for the construction of sluice gate and other related work on Chichirmichchi river, a tributary of Falgu.

The detailed call records of the cellphones of Surendra and complainant Arun Kumar confirmed that the former had made calls to the latter's cellphone around 3pm on Saturday. So he was made accused under Section 387 (extortion) of IPC.

Surendra had courted controversy last December after being thrashed by a group of shopkeepers on Tekari Road in Gaya town for beating up the owner of a tilkut shop.

The agitated traders had also poured hot water on the MLA, who, in turn, ordered his bodyguard to thrash the shopkeeper.

A case was lodged against Surendra for beating up the doctors of AN Magadh Medical College and Hospital in 2011. "He is a habitual offender," said a police officer, who had earlier served as Gaya SP.
