Delhi Police is investigating a case of blackmailing of young sitarist and legendary musician Pandit Ravi Shankar's daughter, Anoushka and has arrested a Mumbai-based man who allegedly accessed her photographs stored in her laptop.

The man, whose identity has not been revealed, has been arrested by the Special Cell of Delhi Police following investigations in Mumbai after Ravi Shankar approached police last month complaining about the harassment meted out to his daughter, a senior police official said.
