A Louisiana man who allegedly threatened to kill members of his family was arrested Thursday night in Hackett with what appeared to be tools to carry out his threats.

About 8 p.m. Thursday, Hackett police arrested Robert Gray, 26, of Darrow, La., on a felony warrant for first-degree terroristic threatening, according to a news release from Lt. Philip Pevehouse with the Sebastian County Sheriff’s Office.

Gray had traveled from Louisiana to Hackett in an effort to find his estranged wife. His wife was not in the Hackett area, nor is her residence near Hackett, the release states.

According to the release, Gray approached Hackett police officers to ask for his wife’s address. The Hackett Police Department had received information on Gray and recognized him immediately. He was arrested without incident.

Authorities searched Gray’s vehicle and found plastic bottles of gasoline, butane lighters, zip ties, duct tape, rubber gloves, a ball-peen hammer and a small hacksaw in a backpack. The Fort Smith Fire Department’s bomb squad assisted with rendering the flammable liquid safe, the release states.

Investigators with the Sheriff’s Office interviewed Gray. He was booked into the Sebastian County Adult Detention Center without bond, according to the release.

The investigation is ongoing, the release states.

The Sheriff’s Office previously received a report that Gray had threatened to kill his estranged wife, who resides in Sebastian County, their children and her parents. Gray had also threatened to burn down his estranged wife’s home.
