The personal assistant of Samajwadi Party MLA Abu Asim Azmi approached police claiming he had received threatening phone calls over the party opposing the renaming of Aurangabad and Osmanabad as Sambhajinagar and Dharashiv respectively, an official said on Monday.

Hours before Uddhav Thackeray resigned as Maharashtra chief minister on June 29, the Maha Vikas Aghadi cabinet, which also included Congress and NCP ministers, approved the renaming of Aurangabad as Sambhajinagar and Osmanabad as Dharashiv.
