A staff at PTT said that all who do not need to stay are allowed to go home, as the complex gets ready for a protest against LPG price hike.
The protesters could arrive in front of the complex at 3.30pm, he said.
The complex houses a number of buildings, including PTT's headquarters. Next to it are Energy Complex, where the Energy Ministry is located along with some energy companies. The Board of Investment's building is also at the complex.
