Suspect in Kim Jong Nam attack says she got $90 for a prank

Siti Aisyah also told authorities she did not want her parents to see her in custody, Andriano Erwin, Indonesia's deputy ambassador to Malaysia, said one day after Malaysia revealed that VX nerve agent was used in the bizarre killing at Kuala Lumpur's airport.

North Korea, a prime suspect in the case, never signed that treaty, and has spent decades developing a complex chemical weapons program.

Senior police official Abdul Samah Mat, who is handling the investigation, did not specify what authorities found there, but said the items were being tested for traces of any chemicals.
