Federal authorities are investigating why a 17-year-old had a pressure cooker and other items used to make an improvised explosive device in his vehicle during a traffic stop in Archer County.
According to Lieutenant Simon Dwyer with the Archer County Sheriff's Office, last Friday, deputies stopped a car westbound on US 82 near Republican Rd. just west of Holliday.
Deputies say the teen was acting very nervous and making strange comments about religion.
The driver told authorities he was from the Fort Worth area and said he was driving to Colorado.
Deputies say they found a pressure cooker, electrical connectors, fertilizer, fireworks, and other items that "could be construed as being components to an improvised explosive device."
They say they also found Pakistani and Islamic literature and drug paraphernalia in the vehicle.
Dwyer says the teen was arrested on other charges at the time and a federal agency was contacted.
Archer County Sheriff Staci Beesinger says the FBI was called because of the suspicious items.
She says federal agents interviewed the teen for a few hours and determined he was not a threat.
Agents determined the teen was using the pressure cooker to grow mushrooms.
Beesinger says the teen had eaten mushrooms earlier in the day and that's why he was making strange comments.
The teen was released to his parents on Sunday on a $4,000 bond.
