Thai police said on Sunday they had uncovered a plot to assassinate the country’s prime minister after seizing a weapons cache belonging to a fugitive anti-junta activist. It is the latest discovery of a weapons stockpile belonging to a member of the red shirt movement, a political group loyal to exiled Prime Minister Thaksin Shinawatra. Police on Saturday found dozens of rifles and grenades, and thousands of rounds of ammunition, at a house belonging to red shirt leader Wuthipong Kochathamakun, who has been on the run since the military coup. Police also arrested nine men in connection with the arms seizure, saying they had clear evidence the suspects and their extended network were aiming to cause unrest. Police said the group was planning an ambush if officials had continued their operations against an influential nearby Buddhist temple, which is seen as having close ties to Thaksin. Thai police ended their search of the Dhammakaya temple earlier this month after laying siege to it for more than three weeks without finding the former abbot, who is wanted for suspected money-laundering.
