New Delhi, March 30 (IANS) A Tihar jail inmate has informed the Central Bureau of Investigation (CBI) on the alleged use of satellite phones and electronic gadgets used in the prison premises, a CBI official said here Friday.

Charanjeet, a prisoner, had claimed in a city court Wednesday that Abhishek Verma, accused of leaking classified information on the navy, and Romesh Sharma, an alleged associate of mobster Dawood Ibrahim, used satellite phones in the jail.

Charanjeet also told the court that he had important information that would assist the investigations into allegations against Verma.

"On the basis of his allegations, we talked to him for an hour. The details provided by him are to be verified," the CBI official told IANS.

However, the high-security Tihar Central Jail had Thursday denied allegations that prisoners were using satellite telephones in its premises.

"The allegations made against the duo are completely baseless as mobile phones are not permitted inside the prison. Along with the other prisoners, their cells are searched twice a day," Tihar spokesperson Sunil Gupta said.

He added: "(The allegations are) in retaliation to an earlier complaint filed against him (Charanjeet) by Verma. He is creating a false story to postpone any court action against him."

Verma had earlier alleged that his political and business rivals were plotting to kill him inside the jail. He said in a March 9 letter to jail officials that four inmates - Charanjeet, Hari Krishan Sharma, Shiv Singh and Kishan Solanki - attacked him with chemical-laced water while he was returning from the Patiala House court.
