The important arrest was made last night during a search operation in Karachi Gulshan-e-Iqbal’s block 13-D area.
The police described it as a major breakthrough in Sabri murder probe.
According to the reports, law enforcement agencies raided a house in Gulshan-e-Iqbal area of the metropolis and picked up the suspect for further investigation.
The identification of the suspect has been kept secret due to the sensitive nature of the high-profile case.
Earlier, Amjad Sabri was gunned down in broad daylight in Liaquatabad area of Karachi when he was on his way along with a companion to a TV channel for participating in its Ramazan transmission.
He was heading to Hasan Square in his car when gunmen riding on a motorbike attacked him. The assailants fired five shots, while one that hit Sabri’s head took his life.
Sindh Inspector General (IG) of police A.D. Khawaja had already claimed that police were close to the killers of Amjad Sabri.
Police teams have been dispatched to interior Sindh to arrest other suspects involved in Sabri’s assassination.
Sabri’s murder became a high-profile case after Governor Sindh, Chief Minister Qaim Ali Shah and other members of the civilian and military leadership promised to bring his killers to book.
