New Delhi: Security agencies have decided to bring arrested gangster Chhota Rajan here with CBI keeping him in custody for initial period before any other police force is allowed to take him for their respective investigations.

Sources said it has been decided that Rajan will not be taken directly to Mumbai from Indonesia, where he was arrested last week. Security arrangements are being beefed up at the agency headquarters where Rajan is likely to be kept with regular security drills being carried out to identify any possible loop hole in the security apparatus, they said.
