The RS MP was arrested from a polling booth in Sambal LS seat on May 10 on charges of intimidation and assault of voters.
National Security Act has been invoked against controversial Rajya Sabha Member DP Yadav who was arrested from a polling booth in Sambal Lok Sabha constituency on May 10 on charges of intimidation and assault of voters, official sources said on Friday.
Yadav, who contested from Sambal where Uttar Pradesh Chief Minister Mulayam Singh Yadav's brother was also in the fray, was arrested on the polling day in Babrala in the constituency on a complaint by former MLA Rishipal Singh Yadav.
The sources said since NSA has been slapped on Yadav, he could not be released on bail now.
Over two dozen criminal cases were pending against the Rajya Sabha Member at various places in Uttar Pradesh, including Ghaziabad, they said.
Meanwhile, Yadav's family members have approached the President and the National Human Rights Commission claiming that he was arrested in a fake case.
