Malappuram (Kerala) | A major drug bust took place at Karipur International Airport in this district, and four people, including a woman, were caught with nearly one kilogram of MDMA, a powerful illegal drug.

Police said on Monday that the woman, 25-year-old Surya from Pathanamthitta district, was arriving from Oman.

Acting on a tip-off, police carried out a surprise check outside the airport on Sunday night.
