The National Police have again warned the public not to make false reports on the whereabouts of explosives or bomb threats.
"We have warned people many times. Don't make jokes about bomb threats or having explosives or other dangerous chemicals," police spokesman Brig. Gen. Agus Rianto said on Thursday, as quoted by kompas.com.
He said anyone falsely claiming to have explosives could be jailed for up to 15 years.
A passenger on Cathay Pacific flight CX718 bound for Hong Kong on Thursday morning joked that he was carrying explosives, causing a 30-minute delay in the departure from Soekarno-Hatta International Airport.
The passenger, identified as Djoni Suyanto, was removed from the flight but was not arrested.
In the hours immediately after the terrorist attack in Central Jakarta on Jan. 14, many hoax messages were disseminated throughout social media that explosives had also been planted in a variety of locations in Jakarta, which subsequently led to misleading and confusing reports in the mass media.
