WATCH: Man accused of aiming flamethrower at officers serving eviction notice in wild bodycam video

A routine eviction call turned into a fiery standoff when an Oklahoma man allegedly blasted deputies with a makeshift flamethrower while a wired car-battery device sat inside his apartment, body-camera video shows.

Body-camera video released by the Oklahoma County Sheriff’s Office captures deputies forcing their way into the dark, cluttered Oklahoma City apartment on Aug. 11 after the tenant, identified as Darron Dunn, 61, allegedly barricaded the entrance.

Deputies had arrived to serve an eviction order shortly before noon. Housing Authority staff unlocked the door, but it would not open all the way. Officers said they found cables connected to the door and an electric wheelchair positioned behind it.

Once inside, a deputy spotted Dunn sitting in a bedroom. The incident report notes Dunn immediately sprayed an aerosol can toward the deputy and a Housing Authority security officer, then allegedly lit it on fire.

The bodycam video showed a bright orange flash as the burst of fire filled the doorway.

"Back up!" an officer can be heard yelling as deputies retreated.

Authorities said the deputy felt the "extreme heat" from the flames. The sheriff’s office said the fire traveled about 15 feet in the deputy’s direction.

But the flames were only the start.

As deputies backed out, officers spotted a car battery with wires attached near Dunn, and another wired device near the front door. The video captured the growing alarm inside the apartment.

"He’s got it hooked up to the battery!" one officer shouted.

"Everybody out! Improvised device! Get out!" another could be heard yelling.

According to the incident report, the device consisted of rows of butane lighter-fluid and carburetor-cleaner aerosol cans taped together with bare wires attached. 

Deputies evacuated residents from the third floor and nearby levels while the sheriff’s tactical team and bomb squad responded.

Officers later disabled the wires connected to the cans and safely removed Dunn from the apartment in his wheelchair, authorities said.

A spokesperson for the Oklahoma County Sheriff’s Office told Fox News Digital that bomb technicians determined the wired aerosol-can device was unlikely to explode as configured. The spokesperson said it could have sparked or heated up if the bare wires touched the car-battery terminal, but technicians did not believe it would detonate.

Dunn was taken to a VA hospital because of medical issues and stress before being placed in a mental hospital, according to the incident report.

Out-of-custody charges were filed against Dunn for assault and battery with a dangerous weapon; possessing, using, manufacturing or threatening to use an incendiary device or explosives; and obstructing an officer.

The sheriff’s office spokesperson said evictions can be "so emotionally charged" and deputies sadly see volatile reactions during such calls. The spokesperson said the confrontation came four years after officers were attacked in another similar eviction-related incident.

In a separate eviction call about a year ago, the spokesperson said, a man allegedly tried to set a deputy on fire before setting himself ablaze and dying.
