WATCH: Terrifying moment spear-wielding man lunges at California cops before shots ring out

An armed man's confrontation with Oakland police came to a deadly end after he ignored repeated commands to drop a collection of weapons and lunged at officers, authorities said.

Dramatic video captured the minutes leading up to the shooting of Jose Angel Castillo, 43, who authorities alleged was carrying two makeshift spears when officers encountered him near a homeless encampment at 40th Avenue and International Boulevard, according to KTVU.

The video shows officers trailing Castillo down the street and repeatedly ordering him to drop the weapons before gunfire erupted.

Video of the ordeal begins with a request for backup as an officer reports being with a man armed with two knives and behaving aggressively.

As police confront him, officers can be heard ordering him to drop multiple objects, including what one officer identifies as a hammer, offering an early glimpse at the array of weapons involved in the encounter.

"We're out with the subject holding two knives, being aggressive," an officer can be heard telling dispatch.

The footage then captures officers repeatedly ordering the man to drop what he is holding as the confrontation escalates.

"Drop that too." Moments later, an officer tells the man he is being detained and orders him to put the weapons down.

"You need to drop those right now.

We're the police, man," the officer says.

As the encounter intensifies, an officer radios that they have a "subject holding two knives" while another can be heard shouting, "Drop the knife!"
