Rehman and his fellow lawyer were sitting with a client in their private chamber near Kutchery Square when unknown armed gunmen entered their chamber and opened fire on them, injuring Mr Rehman and two others.
Rehman was representing Junaid Hafeez who had been accused of a blasphemy, and a lecturer at Bahauddin Zakariya University who is currently facing trial on blasphemy charges.
Rehman, who was also a coordinator for the Human Rights Commission of Pakistan (HRCP) in Multan, had last month been threatened inside a courtroom in the Multan Central Jail.He had been attacked five times before Wednesday.However, he had manage to survive till now.
ASP (Assistant Superintendent Police) Cantt Ali Mardan Khosan said that he knew of the threats to Rehman, and that they were investigating the incident.
The lawyers, who represent blasphemy accused and advocating against the misuse of blasphemy law ,are often being threatened to be killed by extremists and many have left the country to save their lives.
"On Tuesday,a Senior Christian Lawyer,Rana Latif Anwar very serious instructed me that I have to be careful because of my advocacy in blasphemy cases and particularly in the case of Asia Bibi and he also suggested me to arrange some security measures in my chamber," said Gill.
Advocate Sardar Mushtaq Gill ,a Human Rights Defender and Chief of LEAD and its staff,who himself under threats,strongly condemns the killing of HRCP's Advocate Rashid Rehman."We also do not know when and where we will be killed due to our human rights work in Pakistan but such deadly and threatening incidents will not make us discourage in our Human Rights Work," added Gill.
