A California man has been arrested after he allegedly pulled a gun on a white activist who was guarding a Black Lives Matter mural.
The incident occurred Sunday in Martinez, northeast of San Francisco, when Joseph Osuna, 30, drove past the mural, which had been painted outside the city courthouse with government approval.
According to reports, Osuna wound down the window of his Jeep and yelled 'All lives matter', before he made an obscene gesture and sped off.
The white activist who was threatened told ABC7 that he decided to chase after Osuna on his skateboard in order to obtain his license plate and report him to police.

'Immediately a cop was behind him and pulled him over. Thank God!'

Joseph Osuna, 30, was arrested Sunday after he allegedly pulled a gun on a white activist who was guarding a Black Lives Matter mural
He was arrested without incident, and has been charged with brandishing a weapon, NBC reports.
One bystander told the news network: 'This is horrible. He exacerbated the situation. He knew what he was doing. He knew people were over here just protesting. And he came over here with that mentality. With a gun! Who left the house today with a gun? None of us did.'
The white activist who was threatened was guarding the Black Lives Matter mural after it been partially painted over the previous day by a pair of Trump supporters.
During that incident, the couple - who were clad in Trump 2020 merchandise - attempted to conceal the mural's bright yellow lettering with black paint.

The Martinez Police Department is still looking for the couple, who were filmed in the act.
In one video of the incident, a bystander asks the woman painting over the mural 'What's wrong with you?', before her male companion replies: 'We're sick of the narrative, that's what is wrong.'
'The narrative of police brutality, the narrative of oppression, the narrative of racism, it's a lie,' the man adds.
The man, who was recording the incident, then points to the Black Lives Matter sign and calls it 'racism'.
An argument is sparked between the man and onlookers while the woman continues to paint over the mural.
'There is no oppression. There is no racism,' the man says. 'It's a leftist lie...from the media.'
The woman then becomes enraged at the witnesses and exclaims 'keep that s****' in f****** New York! It's not happening in my town!'
The woman appeared to referencing to a number of Black Lives Matter murals approved across all five boroughs of New York City.
Mayor Bill de Blasio announced that one would be painted directly in front of Trump Tower on Fifth Avenue - a move that angered the president - but it was delayed last week for unspecified reasons.
Several such murals have painted on roadways across the country to show solidarity with the Black Lives Matter movement after the killing of George Floyd and other black Americans at the hands of law enforcement.
