A blue sedan drove into a group of people who were protesting Trump’s immigration policy, outside Congressman Ed Royce’s (R-CA) office in Brea, California, on Thursday.

The incident was captured on video at 12:30 p.m. local time (3:30 p.m. EDT), when police were in the process of trying to clear the intersection, where hundreds of protesters were marching in a circle. The protesters were trying to get their message, of what losing their immigration status would mean for them, across to Royce.

That is when a car began pushing through the assembled protesters, driving at a low speed. A few of the people tried to stop the car and one protester even perched herself on the hood, after which the car started going faster. As soon as the car sped up, many protesters were heard screaming at the driver.

The man was stopped by the police a short while later, in the middle of the intersection and one of the police officers approached the vehicle and hit it with a nightstick. There have been no confirmed reports of any injuries incurred due to the incident so far, although, David Huerta, president of the SEIU United Service Workers West labor union, said “several” of his members went to the hospital, LA Times reported.

Daniel Wenzek, the driver of the blue sedan and a 56-year-old Brea resident, was arrested on suspicion of assault with a deadly weapon. He was since released pending further investigation.

46-year-old Claudia Aguilera was the protester who had jumped onto the hood of the vehicle for a few seconds.

“My only thought is that I just want him to stop,” Aguilera said by phone. “I’m like, if I just jump on the car, he’s going to stop. He did stop, thank God, because if he didn’t stop, he would [have] run over a lot of people that [were] crossing the street. It was so quick.”

Royce’s spokesman Steven Smith said that the congressman “condemns in the strongest possible terms any and all violence” and that his staff “remain committed to meeting with all constituents who wish to voice their opinions in a civil and respectful manner.”
