About seven persons, including two women, suffered injuries when the activists of the YSR Congress Party (YSRCP) and the Telugu Desam Party (TDP) clashed in two incidents in Prakasam district.
The injured were admitted in the Government Medical College (RIMS) and their condition is stated to be stable, said the police.
Trouble broke out when the supporters of TDP leader Damacherla Janardhan raised an objection alleging that a woman volunteer, Srujana Priya, was seen campaigning for the YSRCP at Samatha Nagar in the town in favour of Balineni Srinivas Reddy, on Wednesday night. The TDP leaders allegedly tried to take photographs of the YSRCP campaign.
