Arizona authorities have arrested an 18-year-old Phoenix man in connection with a bomb threat that was tweeted after the Jodi Arias verdict was announced.

Maricopa County Sheriff's Deputy Joaquin Enriquez says Laquint Cherry was taken into custody early Thursday. He's facing a felony charge for making threats.

The investigation began Wednesday night after someone tweeted that an explosive device was going to be placed in the courtroom and was going to detonate Thursday afternoon. The sheriff's office increased security and conducted additional bomb sweeps but found nothing.

Enriquez says detectives traced the Twitter activity to a hotel in west Phoenix. The bomb squad and the SWAT team responded, and Cherry eventually came out of the hotel room. A woman who was with him was questioned and released.

Enriquez says the investigation is ongoing.

It wasn't immediately clear if Cherry had legal representation.
