Unidentified gunmen killed a lawyer and injured his aide in Attock on Thursday.
The deceased is identified as Advocate Atif Ali Qureshi.
The lawyers and relatives of Atif Ali staged a protest by placing the body on Rawalpindi Road.
The protesters raised the demand for justice.
The lawyers lashed out at the government for their failure to maintain law and order.
Last month, a woman lawyer fell victim to a gun attack.
