In a Facebook post, Singapore's Defence Minister Mr Ng Eng Hen said two Republic of Singapore Air Force F-15SG jets were scrambled to escort a Scoot flight from Cebu to Singapore after a bomb scare on Sunday.
The bomb threat was later discovered to be a hoax.
Local media reports noted that a 13-year-old boy onboard the flight was allegedly behind the bomb scare. The teen is currently assisting with police investigations.
"The SAF takes every threat as real and seriously until proven otherwise. The RSAF will stay ever vigilant,” Mr Ng said in his Facebook post.
Flight TR385 from Cebu to Singapore eventually landed safely at Changi Airport at 4.49pm, according to a Scoot spokesperson. All 144 passengers and six crew members disembarked from the plane safely.
The spokesperson added, "Scoot will cooperate fully with the authorities in their investigations."
