Celebratory New Year firing in the metropolis left 29 people injured, including two women, police said on Wednesday.
The injured were transported to Civil Hospital, Jinnah Hospital, and Abbasi Shaheed Hospital for treatment.
Rescue sources said that stray bullets hit people in Liaquatabad, Gulshan-e-Iqbal, Shah Faisal Colony, and Orangi Town.
Law enforcement took action, arresting 30 individuals involved in aerial firing. The Karachi police had earlier issued warnings, saying that anyone caught firing in the air would face charges of attempted murder.
In Lahore, meanwhile, several individuals were also arrested for violating laws under the guise of New Year celebrations, the police said. The crackdown followed incidents of aerial firing and hooliganism in various parts of Lahore.

Further arrests were made in Cantt, Hanjarwal, and Shahdara, where individuals were detained for engaging in hooliganism. Similarly, in Shafiqabad and Ichhra, suspects were taken into custody for participating in aerial firing and disruptive activities.
