The Special Cell of Delhi Police arrested the man following investigations in Mumbai after Ravi Shankar complained to the police last in Aug 2009, about the harassment, a senior police official said.
Police registered a case under Section 386 of Indian Penal Code which, relates to extortion by putting in fear of death or hurt and provides for a punishment of maximin of 10 years in jail.
Pandit Ravi Shankar informed that Anoushka had given her laptop to a service centre in south Delhi in Feb 2009.
"We think that the material in the laptop was copied by someone. We interrogated the staff at the Apple Services Centre. Later, we zeroed in on the Mumbai-based man and arrested him," the police official said.
Apparently, the man sent a series of e-mails to 28-year-old Anoushka even demanding USD one lakh for not publicising the photographs.
