In its email to the Belgian Embassy, to inform the officials there about the arrest of their countryman, the Amritsar police have said that 17-year-old Amritpal Kaur was strangled with suitcase strings by her stepfather Mehtab Singh. Mehtab, an NRI from Belgium, was arrested on Tuesday night, soon after an email from Amritpal’s boyfriend Lakhwinder Singh arrived from Belgium, telling cops about the murder. The victim was allegedly killed on the intervening night of June 25 and 26 and quietly cremated in the Shivpuri cremation grounds the next morning, sources said. The suspected honour killing of a middle-school student, who fell in love with a boy of a different caste has shocked everyone. The victim’s boyfriend, Lakwinder Singh, who apprehended murder and sent an email to the Amritsar police, said he met Amritpal on the net, when they were barely into their teens.
