The city police on Friday arrested a 32-year-old astrologer for sexually assaulting an IT engineer when she consulted him last month ‘for solving a personal problem’. The woman had filed a complaint against the astrologer, who was identified as Nilambar Pani, on Thursday, alleging that besides assaulting her, he demanded Rs 2 lakh from her as extortion. “Based on the complaint, we arrested the man from his house in Bhadrak district,” additional deputy commissioner of police Tarun Kumar Das said.
