Wednesday’s killing of Rashid Rehman in the southern city Multan of was the first time a lawyer has been killed for taking on a blasphemy case, police said.

Rehman had been representing Junaid Hafeez, a lecturer in English accused by hardline student groups of making blasphemous remarks against the Prophet Mohammed in March last year.

Hafeez had been in prison without being able to find a lawyer until Rehman agreed to represent him in February.
