CBI sources said suspect John Morrison was arrested in a separate case of allegedly duping another woman and it was during this probe that the agency received another complaint against him from a noted fashion designer based here.
The sources said the fashion designer wants her identity to be kept under wraps because of security concerns.
They said Morrison allegedly met her through Facebook posing as citizen of the United Kingdom and the organiser of London Couture week and promised to promoter her creations at international level.
They said one day the designer claimed to have received a call from a girl claiming to be Customs officer. The girl from Northeast, believed to be close associate of Morrison, told the designer that Morrison has been taken into custody.
She allegedly told the designer that she should deposit Rs 4.10 lakh in three different accounts if she wanted release of Morrison, they said, adding that transfers were made.
