The victim's father had complained to the Cyber Crime Police that his daughter's morhped pictures had been sent to the mobile phone of her would-be husband from an unidentified number.
Text messages running down her character and advising not to marry her accompanied the pictures.
The probe led the police to Madala Ravi, a medical practitioner and resident of Film Nagar.
He had sent the morphed pictures of the girl from his wife's mobile phone, said Additional DCP (Crime) G Janaki Sharmila.
