Cuttack, Feb. 20: The Dhal Samant brothers today refused to give their consent to a voice test in the alleged kidnapping and murder of their aides, Dipu and Om.

The duo's voice samples were needed to match it with the audio recording of an alleged telephonic conversation between them and their deceased aides.

Chauliaganj police station inspector-in-charge Ajay Kumar Das had filed a petition in the court of the sub-divisional judicial magistrate (SDJM), Cuttack, to take the brothers' voice samples as part of the probe into the kidnapping and murder.

The SDJM had allowed the plea and had directed the police to produce the brothers today to seek their consent for the test. "Both of them refused to give their consent when we produced them before the SDJM," said assistant public prosecutor Biswajit Baral.

The brothers - Sushant and Sushil - have also refused to co-operate in the investigation and police sources conceded that corroborating evidences for the trial in the case may not be easy as they thwarted attempts for both polygraph and voice tests.

Police commissioner Y.B. Khurania said: "We gave the Dhal Samant brothers a chance to come clear by taking the polygraph and voice tests. Now, that they have refused to give consent, presumption will go against them."

Marik denies link

In another development, former director general of police Sanjeev Marik today denied the allegation levelled by former IPS officer-turned-politician Anadi Sahu that he had links with the Dhal Samant duo. "His allegations are false. He is doing this only for publicity," said Marik.

Earlier in the day, Sahu had alleged that Marik had links with the gangster siblings and had even received money from them.

In yet another development, police today raided the house of Jugaprakash Kanungo, another aide of the gangster brothers, at Sutahaat area in Cuttack and seized a pistol and fifty live bullets. Khurania added that Kanungo was involved in tender fixing and various other criminal activities.
