The bruised and battered family of Muhammad Yousaf, victim of the attack that left at least 72 people killed and over 250 injured, said that the police added insult to their loss by detaining some of its members, Dawn online reported.
Police had detained members of Yousaf's family after mistakenly declaring him the suicide bomber during frantic search for clues after Sunday's blast.
Jamaat-ul-Ahrar, a faction of the Pakistani Taliban, claimed responsibility for the attack and said it deliberately targeted Christians celebrating Easter.
Jindan Mai, mother of Yousaf, narrated her ordeal and said that she can never forget the treatment Yousaf's family was subjected to by police who harassed and locked them up.
She said that her pleas that the family was innocent fell on deaf ears.
Soon after the blast, police raided Yousaf's home and arrested three of his brothers and locked the women inside.
His family members were freed on Wednesday and they went to Lahore to receive the body.
On Thursday, hundreds of people attended the funeral of Yousaf as he was laid to rest.
Yousaf had gone to Lahore and visited the park with his friends Bilal Shakir and Qari Yaqoob, both from Dera Ghazi Khan city. Bilal also died while Yaqoob was injured.(IANS)
