After being imprisoned for more than 15 months, former telecom minister A. Raja walked out of Tihar Jail on Tuesday. He was granted bail in the 2G spectrum allocation case earlier in the day but with the rider that he could neither visit the Department of Telecommunications (DoT) or his home state of Tamil Nadu.

Raja, the last of the 14 individuals charged in the case still in prison, was given bail on a surety of Rs.20 lakh by Central Bureau of Investigation (CBI) special judge O.P. Saini. He is expected to be released from jail, where he has been since February 2011, on Tuesday evening.

"Considering the progress of the trial, period of custody of the accused and the fact that all other accused have been released on bail, I am of the opinion that further detention of the accused would not serve any purpose and, for these reasons, I am inclined to grant applicant (Raja) bail," the judge said.

He also directed that Raja could not visit the department of telecommunications or Tamil Nadu without the court's prior permission.

The announcement that Raja, who has been behind bars in the capital's Tihar Jail, was granted bail triggered wild slogan shouting and cheering by his DMK supporters, mainly from Tamil Nadu, who raised slogans in Tamil like: "Raja, vazhga!" (long live Raja!)

The DMK also expressed confidence that he would come out clean. Besides the 14 individuals, three companies were also charged in the case related to 2G spectrum licences allocated during his tenure as communications minister.

"We are happy. Getting bail is part of the legal process. We are confident that Raja will come out clean in the whole episode," DMK spokesperson T.K.S. Elangovan said.

There were also celebrations in Raja's home town Perambalur, around 300 km from Chennai.

The court issued its releasing order after DMK MP from Kallakurichi, Adhi Shankar and Rajya Sabha MP Tiruchi Siva furnished Raja's bail bond of Rs20 lakh.

The court also imposed condition on Raja that he would not directly or indirectly make any inducement threat or promise to any person acquainted with the facts of the case.

Raja will remain present before the court on all dates fixed for hearing of the case either personally or through his counsel.

Giving details of what had transpired, Raja's counsel told reporters that the judge called Raja towards him and told him: "Your bail application is allowed."

"Raja had not moved bail until all other 13 were granted bail," he added. "Now all the accused are on bail. The case will go on."

The counsel pointed out that Raja had got bail despite the CBI's opposition.

The CBI had opposed Raja's bail application, saying he faced charges of accepting bribes of Rs200 crore, which makes his case different from former telecom secretary Siddharth Behura, who was granted bail by the Supreme Court last week.

Raja, in his bail application, had requested the court to release him on the ground of parity.

The agency told the court that if the accused was released on bail at this crucial stage of trial, then he may influence the vital witnesses as some of them belong to Tamil Nadu.

Raja resigned as minister Nov 14, 2010 in the wake of the Comptroller and Auditor General reporting that his 2008 decision to allocate 2G spectrum on a first-come-first-served basis had caused the exchequer a presumptive loss of Rs 1.76 lakh crore. The CBI arrested him Feb 2, 2011.

The Supreme Court in February cancelled 122 spectrum licences allocated during Raja's tenure. It also ruled that all natural resources should be allocated through an auction, which the government is now preparing to do in the case of the cancelled licences.
