A Kansas man accused of planning to detonate a car bomb at a Wichita airport was arrested Friday at the airport, authorities said.

Terry Lee Loewen, 58, planned to drive a car that he believed was full of explosives into a terminal at Mid-Continent regional airport, U.S. Attorney Barry Grissom said.

Loewen was charged with one count each of attempting to use a weapon of mass destruction, attempting to damage property and attempting to provide support to terrorist group al-Qaida. Authorities said he was trying to support “al-Qaida in the Arabian Peninsula.”

Investigators said Loewen is an avionics technician who lives in Wichita and works at the airport. He had been under investigation for about six months after he made statements about wanting to commit “violent jihad” against the U.S.

Authorities said they believe Loewen acted alone. No other arrests are expected.

Wichita Mid-Continent Airport had 68 scheduled commercial flights on Friday, according to flight tracking site FlightAware.com.
