With Police remaining clueless about Thursday’s bus blast at Pipli in Haryana and investigation not progressing much into the incident, Haryana Police has now appealed to the passengers of that bus to cooperate in the investigation.

The State Government has already announced a reward of Rs 10 lakh for any credible information about those involved in the blast in a Haryana roadways bus.

The central agencies—IB and NIA—are working in close coordination with Haryana police's SIT to investigate the explosion incidents. A Special Investigation Team (SIT) was constituted under Haryana Additional Director General of Police (Crime) S S Kapoor to investigate the three cases of explosion that have occurred in Kurukshetra on May 26 and previous explosions happened in Panipat on January 16 and May 13.

A member of Haryana SIT and Superintendent of Police (SP), Kurukshetra,  Simardeep Singh on Monday said that the passengers of the  ill-fated bus should contact the Police with any information regarding the incident which may help in identifying those behind the blast.

About 25 passengers were on board the Haryana Roadways bus at the time of the blast while the police have been able to access only the eight who were injured.

The teams of IB and NIA had on Friday visited the site of the “low intensity” blast which occurred near Pipli when the bus was on its way to Chandigarh from Sonepat. Around eight people were injured in the explosion in which IED was suspectedly used.

Earlier on May 13, a blast had taken place in a bogie of a Delhi-Panipat passenger train causing minor injuries to a

15-year-old boy.

The blast took place when the train was parked in the yard in Panipat.  The earlier blast had happened in January in the

Panipat-Ambala (64543)

passenger train

stationed on the platform.

Forensic experts are already analysing details to establish the pattern of the Pipli blast with two recent similar incidents at Panipat railway station.

According to investigators, the bomb in the Haryana roadways bus was packed in a yellow poly-bag with Western Union and a few lines in Thai written on it. Examination of the bomb has also revealed that easily available firecracker ingredients - potassium

chlorate, sulphur and

ammonium powder - were

used as explosives.
