A suspected cocaine dealer was arrested last week after authorities say he assaulted an officer and an assault rifle was found in his home.

Deion Dawson, 28, of Ojai was arrested on the evening of April 5 on the 600 block of Grand Avenue in Ojai.

According to the Ventura County Sheriff’s Office, Dawson was the subject of a monthlong investigation into allegations that he was dealing cocaine out of his home on the 400 block of East Oak Street.

Narcotics detectives from the Sheriff’s Office said they developed probable cause to arrest Dawson for drug trafficking, and a search warrant for his home and vehicle was authorized by Ventura County Superior Court judge.

Last Friday, deputies, with assistance from the Ojai Police Department, arrested Dawson in his vehicle. During the arrest, the Sheriff’s Office alleges Dawson assaulted one of its detectives who ended up receiving medical treatment on site.

Authorities served the search warrant at Dawson’s property, where they recovered more than four ounces of cocaine, two ounces of psilocybin mushrooms, a half-pound of marijuana and a large amount of cash believed to have been the profits from drug sales. They also found an unregistered assault rifle.

Dawson was booked into the Pre-Trial Detention Facility in Ventura where he awaits multiple felony charges including narcotics sales, battery of an officer and unlawful possession of a firearm.

He’s due in court on April 24 and is currently being held on $50,000 bail.
