At least three protesters were injured when Thai police fired tear gas and rubber bullets at a Bangkok rally held against Prime Minister Prayut Chan-ocha.
For the third day in a week, protesters and police clashed last Friday.
Thailand is grappling with its worst virus outbreak so far and registered a new daily high of 23,418 infections.
The sluggish rollout of Thailand’s vaccination programme and financial pain from restrictions is heaping political pressure on the prime minister.
Protesters gathered in Bangkok at a major intersection by Victory Monument and set fire to sacks of rotting fruit to symbolise the economic hardship of farmers.
Demonstrators attempted to march on Prayut’s residence inside a military barracks holding a large banner that read, “Prayuth must get out immediately.”
Police used barbed wire and rows of shipping containers to block their path while officers fired tear gas, rubber bullets and water cannon.
Deputy National Police spokesman Kissana Phathanacharoen said protesters targeted officers with ping pong bombs, slingshots, bricks, and firecrackers.
At least three protesters were injured including youth activist Thanat “Nat” Thanakitamnuay.
Bangkok police, facing accusations of heavy-handedness, have insisted their approach is in line with the law and urged people not to jeopardise public health and safety.
“There is clear evidence that some people among the protest group have contracted COVID-19,” Metropolitan Police Bureau chief Phukphong Phongpetra told reporters on Friday.
