Long-absconding underworld don Rajendra Nikhalje alias Chhota Rajan on Friday was brought to New Delhi from Indonesia, officials said.

Rajan, who was arrested by Indonesian police on October 26, reached here in a special aircraft around 5.30 a.m. at Palam airport from where he was taken to Central Bureau of Investigation (CBI) headquarters, escorted by special commandos and SWAT team, police said.

The aircraft carrying Rajan, along with a team of CBI officials and others, had departed for India around 8 p.m. (local time) from Bali, Indonesia on Thursday.

Rajan, 55, reached CBI headquarters around 6 a.m. All routes leading the the CBI headquarters have been sealed by Delhi Police.

Besides, the security of CBI headquarters, which is looked after by the Central Industrial Security Force (CISF), has been increased.

Rajan, 55, who has been absconding from India for two decades was arrested by Indonesian police on a request of CBI in Bali on October 26, following a tip-off by the Australian Federal Police.

Rajan has been kept in a lockup in CBI headquarters, sources said, adding that he will be taken for medical examination soon.

The mafia don will be presented before a special CBI magistrate very soon after his medical examination, who will officially hand over his custody to the investigating agency, sources said.

On Thursday, a senior Maharashtra government official, Additional Chief Secretary K.P. Bakshi said at a press conference in Mumbai that Chhotan Rajan, arrested by Indonesian Police on October 26, was escorted amidst tight security to the Bali airport for a flight to india, which is scheduled to land in New Delhi around 4 a.m. Friday.

He said all the cases pending against the mafia don will be transferred to the Central Bureau of Investigation (CBI) which will now probe them.

With flights resuming from Bali airport after two days of their being suspended because of ash spewed into the air from a volcanic eruption, Chhota Rajan's deportation has finally come about. It had been cleared by Interpol on Tuesday last. 

But Mount Rinjani on Lambok island near Bali erupted on Tuesday morning and the volcanic ash haze had led to cancellation of flights from the Bali airport. 

While earlier reports had said that air services will be suspended till Friday, ANI news agency tweeted on Thursday that the services have been resumed. 

Chhota Rajan is wanted in India for murder and extortion and police are waiting to quiz him on his connections with Dawood Ibrahim and the Mumbai blasts.
