Sources say that Haryana Chief Minister Bansi Lal and State DGP S B K Sethi have taken exception to the frequent references to Haryana every time there is a robbery in Delhi.

‘‘If the Delhi police think that because of the porous borders, criminals are freely entering the Capital, it is not our fault. It reflects bad policing on their part, said an official in the Haryana Government.

Several Delhi police officials have been claiming that after the liquor ban was lifted in Haryana two months ago, bootleggers have shifted to Delhi and are responsible for the spurt in incidents of robbery.

Sethi is believed to have pointed out this to V N Singh as baseless and harming the image of the State. Also, from statistics available with the Delhi police, only 15 per cent of the robbers were found tobe from Haryana.

The contention of the Delhi police that the bomb, which exploded inside a bus at ISBT on July 26, had been planted at Panipat has also come under fire.

The Haryana police say that there are clear indications that the bomb had been planted at ISBT, but the Delhi police are trying to shirk responsibility.

V N Singh could not be contacted despite repeated attempts. But another senior official said that the stand taken by the Haryana police will hamper prosecution.

The working rule so far has been to produce any criminal, caught by either police force, to a court in the city where the accused is arrested. The State from where the accused hails is given a go-by for the sake of convenience. ‘‘Conflicts over custody will lead to bad prosecution, the official says.
