Intelligence Bureau inputs to Delhi police said the six people entered Seelampur area of East Delhi on Wednesday and could possibly carry out strikes in the national capital, police sources said.

The six militants travelled in a white car with a fake registration number from Deoband in Western Uttar Pradesh, the site of the Darul Uloom seminary, to Seelampur area, the sources said.

While one of the passengers travelling in the car was stated to be of African origin, two were believed to be Afghan nationals and the remaining locals, the sources said.

A thorough check was carried out in Seelampur which prominently figured during investigations into recent serial blasts in courts in three cities of Uttar Pradesh--Lucknow, Faizabad and Varanasi.

Police put up barricades along all important crossways and a thorough screening of vehicles was conducted. Suspected pedestrians were being questioned.
