KARACHI: Three people, including a minor boy, were killed in separate incidents involving heavy vehicles in the city early on Thursday morning, said police and rescue services officials.

In the Bufferzone area, a water tanker hit and killed a minor boy.

Taimuria SHO Saqib Khan said the tanker driver had provided water in Nasir Brohi Goth near KBR Society. But as he reversed the heavy vehicle, it hit 8-year-old Saim Rehman, who died on the spot.

The incident angered residents who smashed the tanker and damaged it. The police arrested the suspect driver, who was identified as Sheeraz alias Juma Khan.

In a separate incident, a young man was killed while his relative critically injured in a clash with a 22-wheeler truck on National Highway near Anwar Baloch Hotel, Shah Latif Town SHO Raja Abbas told Dawn. The officer said the victims were coming from Saddar. They were taken to the Jinnah Postgraduate Medical Centre where Mohammed Amir, 35, died during treatment while his brother-in-law, Sajid, 28, was admitted for treatment.

The police had registered an FIR on the complaint of the victim`s brother, Kaleemuddin, against the driver under Sections 320 (grievous hurt), 379 (theft) and 427 (mischief casing damage) of the Pakistan Penal Code.

The third incident occurred on Sharea Faisal where a 19-year-old Bykea rider was killed.

Area SHO Faisal Gul Khawaja told Dawn that victim Shakir Ali`s motorcycle collided with a dumper truck from behind near the National Highway Authority office.
