New Delhi: Delhi Police today sought a fresh undertaking from one of the prominent members of erstwhile Team Anna to allow their dharna here on the coal allocation issue, while warning them against gheraoing the residences of Prime Minister Manmohan Singh and BJP chief Nitin Gadkari.

In an indirect rejection of application for staging a dharna at Jantar Mantar tomorrow, Additional Commissioner (New Delhi) K C Dwivedi said police need a fresh undertaking from “such office bearer”, who can exercise control over everyone participating in the protest.
