A man arrested in Santa Monica allegedly in possession of weapons and explosive materials following the Orlando massacre and before an LGBT parade in West Hollywood is scheduled to appear in court Tuesday.

James Wesley Howell, 20, of Indiana was arrested about 5 a.m. Sunday in the 1700 block of 11th Street, said Santa Monica police Chief Jacqueline Seabrooks. He was being held in lieu of $500,000 bail on suspicion of weapons and explosives possession, according to Seabrooks and jail records.

Howell is scheduled to make an appearance Tuesday at the Airport Branch court on La Cienega Boulevard, according to jail records.

Police said Howell was found sitting in his car when officers responded to a report of a man knocking on a resident’s door and window.

Officers investigating Howell’s white Acura sedan with Indiana license plates recovered three assault rifles, high capacity magazines and ammunition along with a 5-gallon bucket with chemicals that could have been used to make an improvised explosive device, police said.

The sheriff’s department bomb squad was called to help make sure the vehicle and area were safe, police said.

Howell told police he was planning to attend the 46th annual LA Pride parade and festival in West Hollywood, but made no reference to doing harm there, according to Santa Monica police Lt. Saul Rodriguez.

“He did not make any additional statements saying he was going to do anything further than” attend the event, Rodriguez said. Police said Howell and his car were found about seven miles from the event, police said.

Seabrooks and Rodriguez said there was no known connection between Howell and the overnight mass-shooting in Orlando, Florida, where 50 people were killed and 53 wounded in the nation’s worst mass shooting.

Security was increased at Sunday’s LA Pride festival as a result of the Orlando massacre and Howell’s arrest, said Lt. Vance Duffy of the West Hollywood Sheriff’s Station. Santa Monica police and the FBI were continuing to investigate the case.

Howell was arrested less than a year ago for allegedly pointing a gun at his neighbors, according to the Los Angeles Times, which cited Indiana Court records. He was charged in October with felony intimidation and pointing a firearm at another person.

On April 19, Howell accepted a deal in which he pleaded guilty to misdemeanor intimidation, was sentenced to a year in state prison but was placed on probation, the newspaper reported. Howell agreed to forfeit all weapons during probation.

As of this morning. authorities were still trying to determine Howell’s intentions.

Joseph Greeson, 18, a friend of Howell’s and a fellow car club member, said Howell didn’t harbor any ill will toward gays or lesbians and that he is bisexual, The Times reported.
