The suburban Amboli police arrested model Shikha Joshi and her brother for pelting stones at the residence of cosmetic surgeon Dr Vijay Sharma, police sources said.
In 2011, Shikha had filed a case of molestation against the doctor.
Sources said that Joshi and her brother went to the doctor's residence on October 30, and threw stones when the doctor refused to admit them in.
Joshi was called in today for questioning following which she was arrested. They are likely to be released on bail after completion of formalities as the offence is bailable, sources said.
