Bomb-making tips are found on the notebook belonging to Warisriya Boonsom - a suspected mastermind behind the botched bomb attack on the Bhumjaithai Party.
Warisriya, who is now in detention, admitted owning the notebook but denied writing down those tips.
"The notebook was found inside her luggage bag," Department of Special Investigation (DSI) director general Tharit Pengdit said Tuesday.
Warisriya and her husband, Kobchai Boonplod, were arrested in Cambodia last Saturday and were extradited back on Monday. The couple fled out of Thailand on June 23, one day after the bomb attack took place.
