Rowdy anti-government protesters have upstaged efforts by prime minister Yingluck Shinawatra to show normality was returning to Thailand, with another rally.
After initially pledging to stage a peaceful march, protesters knocked over concrete barriers and forced their way into the police compound in Bangkok. But the commotion ended quickly, with police opening the gates to let protesters enter.
Authorities used the same strategy a day earlier at sites where violent clashes had erupted over the past several days between police and anti-government protesters trying to topple the government of Ms Yingluck, who has returned to her office after five days away.
The government's move was timed to coincide with national celebrations for the revered king's 86th birthday tomorrow.
