   Police in India have arrested a Citibank employee accused of cheating clients out of millions of dollars. Shivraj Purl, 32, who will appear in court later, told an Indian newspaper he was innocent. The crime was discovered earlier this month in a branch of the global bank in Gurgaon, a wealthy district of Delhi. The bank has said investors were promised quick, high returns from a false financial scheme. It is claimed that Mr. Purl transferred the money into accounts controlled by three relatives. Mr. Puff reportedly handed himself in on Thursday, a day after police said he was wanted for questioning. The crime was revealed earlier this month when a client mentioned the scheme to a senior bank manager.
