Leaders from LJP and Samajwadi Party, including Union Minister Ramvilas Paswan and SP General Secretary Amar Singh, were on Tuesday prevented from entering Greater Noida where four persons were killed during a farmers agitation.
While Paswan and Singh were stopped at the Delhi-UP border, the LJP chief's younger brother and Lok Sabha member Ramchandra Paswan was taken into custody by the Uttar Pradesh Police.
The leaders were going towards Greater Noida to disburse Rs two lakh as relief to the families of the victims of police firing last week.
Police requested the Minister not to proceed towards Greater Noida following which he and Singh returned.
Singh told reporters that Uttar Pradesh Chief Minister Mayawati was following the same policies of West Bengal Government in land acquisition and said his party would launch a protest in Singur.
The district administration has, however, allowed LJP and SP leaders to disburse the relief between August 25 and 28.
Four persons were killed and 50 others, including 15 policemen, injured in police firing and clashes on August 13 after farmers agitating for adequate compensation for their acquired land in Greater Noida turned violent.
Farmers were agitating for enhanced compensation for their land acquired in 2003 and 2005 by the Uttar Pradesh government on the lines of those acquired in 2008.
