As many as 15 persons were injured on 7 June following an explosion on a private bus in Haryana. This was the fourth such incident in the state this year.
The explosion occurred before 11 am in Fatehabad district on the western edge of the state, around 200 km from Chandigarh.
Authorities said the explosion took place due to the use of sulphur, a key component of firecrackers. A passenger was carrying the said component in a bottle, which caused the blast when it fell, they added.
Police officers along with bomb disposal squad and forensic experts reached the spot and are probing the incident. The explosive device was kept in a black bag.
“Though this incident looks like a mischief but given the fact that three similar blasts have accrued in recent past, we are taking it seriously and the investigation is being conducted,” Ram Niwas, Home Secretary said.
Last month, eight persons were injured in a similar explosion on a state road bus in Kurukshetra, around 220 km from Delhi. Officials had then said the incident was a terror attack and so the probe was given to the National Investigation Agency.
