The first complaint was lodged at the Metropolitan Police Bureau.
Khao Jaengsuk, 39, showed up there on Wednesday's night with bruises all over his left arm and his right arm in soft plaster cast.
He also sustained broken jaw and a shallow knife wound in his stomach.
Khao said six PAD guards attacked him on October 25 accusing him of being a member of an anti-PAD group in Udon Thani.
"They tried to force a confession out of me. But I am not in an anti-PAD group. In fact, I had been attending PAD rally at the Government House since early September," the 39-year-old man said.
He said the PAD guards kicked, punched and threatened him.
"They locked me up in a room but released me the next day," Khao said.
Khao's relatives sent him to the Rajvithi Hospital for treatment.
The second complaint was filed by a taxi-motorcyclist, Am Daosing.
Am, 39, Thursday told police that some PAD guards physically assaulted him on Wednesday after seeing his vehicle sported a sticker emblazoning "Fed up with PAD".
"I took a passenger from Siam Square to the Government House that day. After she got off, I ran into a group of PAD guards at the Chamai Maruchet Bridge," Am recounted, "They pointed at the sticker and dragged him into a room near a shrine".
Inside the room, the guards beat him up while questioning whether he was paid to wreak havoc at the PAD rally.
"They even took away my ATM and forced me to give them the code. After they checked the ATM and found that I had no money, they allowed me to go home," Am said.
The taxi motorcyclist had been detained for more than four hours.
After Am found his left temple swollen this morning, he sought treatment at the Police General Hospital. He then lodged a complaint with police.
"Their actions are so barbaric. We are all Thais. We can talk," he said.
