The assault came a day after the death of Sarabjit singh inside a Lahore jail, where he was attacked by fellow inmates.

Sanaullah’s relatives, brother-in-law Mohammed Sehzaad and nephew Mohammed Asif, who arrived here on Tuesday, visited him on Wednesday for about 10 minutes in the Advanced Trauma Centre of PGIMER.
