A man shot dead his sister due to ‘honour’ in the Sukheke area of Hafizabad, reported the 24NewsHD TV channel on Sunday.
The accused, who was later identified as Adeel, escaped from the scene soon after the murder.
Local police registered a case of murder against the accused on behalf of the victim's father and started an investigation.
Despite the existence of specific laws against honour killings in Pakistan, incidents of "kala kali" in Punjab, "karukari" in Sindh, "tor tora" in Khyber Pakhtunkhwa, and "sayakari" in Balochistan are common.
