We can now bring you some more from Boulder Police Chief Stephen Redfearn, who says the police are currently interviewing witnesses and asks people to avoid speculation.

Videos of the attack circulating online show a chaotic scene near a fountain at Boulder’s outdoor Pearl Street Mall in Colorado.

Smoke can be seen filling the air while people run in several directions. At least two people appear to be helping others who have fallen to the ground.

In the background, part of the grass appears to be on fire, and people can be heard shouting in the background.

A separate video shows police later wheeling people away from the scene on stretchers.

Redfearn says multiple people were injured in the attack but does not exactly how many.

An area hospital received multiple patients, and some were transferred to other hospitals.

Those patients have a range of injuries from “very serious” to more minor.

Officials say there will be another update later tonight.

A reporter asks if police will provide additional security for Jewish and pro-Israeli protesters.

Redfearn says he cannot confirm at this time that this was an attack targeted at a specific group of people, but he understands there are a lot of tensions and issues in the US right now.

He says the police will “react accordingly” once they have a clear motive – including additional security and other measures.

The police chief is continuing to take questions. When someone asks if a Molotov cocktail was thrown in the attack, Redfearn says it’s too early to tell, but says the suspect was “setting people on fire”.

The suspect is an adult male who they are working to identify, he adds.

A reporter asks if a protest was going on when the attack happened.

Redfearn says the area is a “walking pedestrian mall” and was crowded with visitors. He says a group of pro-Israel people were gathered in the mall and were demonstrating peacefully.

He said they are interviewing witnesses to decipher if the group was targeted.

Redfearn is asked if he would call it a “targeted terror attack” as the FBI has and he says that it is “way too early” to speculate on the motive. He says local police are not yet calling it a targeted terror attack.

Chief Redfearn says the scene of the attack is closed off, including businesses, while investigations are ongoing.

He adds that the area is not safe yet and that officers are investigating a “vehicle of interest”.

He says this was a “beautiful Sunday afternoon in downtown Boulder” and this act is “unacceptable”.

Dozens of people are working to figure out what happened, he says, and asks for patience and for people to think of the victims and their families.

Boulder Police Chief Stephen Redfearn says several people were injured in the incident, including injuries consistent with burns as well as other injuries.

He says police found the suspect and took him into custody “without incident”.

The suspect was also taken to the hospital with minor injuries, the police chief says.

He says that they can’t release the suspect’s name yet as they investigate the incident.

Boulder Police Chief Stephen Redfearn is speaking and offering what he calls “very preliminary information” that they received calls about an attack at 1:26 pm local time (20:26 BST).

People who called authorities said there was a man with a weapon and people were being set on fire.

Officers responded quickly, he said.

A news conference is now under way in Boulder, Colorado, after police said multiple people were injured after an incident.
