Thai police fired teargas at protesters blocking the Gate 7 of the Government House on the side of Padung Krung Kasem Canal on Friday morning.
The police fired tear gas at about 11:00 a.m. (0400 GMT) to disperse the protesters.
They removed barriers of the protesters too.
A clash occurred between the two sides while police were removing the barriers.
A larger operation to seize back the Government House which was occupied by the protestors since Aug. 26 was expected.
