BAHAWALPUR, Feb 6: The district police claimed to have taken into custody scores of people in its probe into an alleged sabotage that caused the derailment of Lahore-bound Karakoram Express between Sammasatta and Kalanchwala railway stations on Saturday.

DPO Arif Nawaz said on Monday that four of the suspects were particularly being quizzed.

He said that most of the people in custody were those who had been involved in thefts of the railway material during the last several years.

However, he said the police were conducting its probe keeping in view all possibilities, including sabotage. The railway authorities, it may be added, had lodged a sabotage case with the Musafirkhana police station on Sunday.

Meanwhile, the Federal Government Inspector of Railways (FGIR) conducted inquiry into the derailment at the Sammasatta railway station.

It is learnt that the FGIR held proceedings at the railway rest house in Sammasatta, where no telephone facility was available to know about his preliminary findings.

He will now hold further proceedings in Multan on Tuesday (today).

Meanwhile, passengers Lahore’s Shaheen Bibi and her daughter , who were hospitalised after derailment, were discharged from the Bahawal Victoria Hospital on Monday.
