Long queues were seen at the Delhi airport on Thursday evening as authorities reported an increase in prohibited material that passengers carried with their luggage. The authorities attributed the slow handling of the luggage to “holiday weekend”.

“With onset of holiday weekend, Delhi airport experienced increased level of dangerous goods, particularly power banks and lighters, in luggage,” the Delhi International Airport Limited said in a statement, according to ANI. “Incident rate was 30% higher than average. It impacted baggage handling due to the manual reconciliation of the suspect baggage.”

Earlier, reports said the delays at the airport were because of a system failure. Thousands of bags were reported to be misplaced.

More details are awaited.
