SANTA MONICA, Calif. (AP) — Authorities say they’ll try to revoke the probation of an Indiana man arrested with a cache of weapons and ammunition who said he was headed to a California gay pride parade.

The chief probation officer in Clark County, Indiana, says 20-year-old James Wesley Howell didn’t have permission to leave the state following his guilty plea in April to a misdemeanor intimidation charge.

James Hayden says Howell met on May 22 with a probation officer, who rated him a low-level offender. Hayden says officers hadn’t yet conducted a surprise home visit to check that Howell was following a judge’s order not to have weapons during his one-year probation.

Howell was arrested Sunday in Santa Monica with three assault rifles, high-capacity magazines and ammunition, and explosive chemicals.
