The fugitive Thai wife accused of the hit-and-run death of college student Ben Kable in Michigan was frogmarched through an airport onto a commercial flight today.

Footage shows Tubtim 'Sue' Howson, 57, surrounded by police as she was lead onto a Boeing 737 plane at the Suvarnabhumi International Airport in Bangkok, Thailand, at around 4pm local time. Police are accompanying her onboard the flight and FBI officers are waiting to arrest her in the U.S. as soon as she lands in Michigan.

It is not known if she paid for the ticket herself. She checked in at the China Airlines desk and is believed to be flying across the Noth Pacific Ocean with a connecting flight in Far East.

Howson, who is originally from Thailand but a U.S. citizen through marriage, allegedly mowed down Ben on January 1 as he returned in the morning from a party in Oakland County. She turned around and returned home then later bought a one-way ticket from the Detroit Metro Airport with a layover in Dallas-Fort Worth before arriving in her homeland on January 5.

FBI officers working with Thai police tracked Tubtim down to a house in Ratchaburi province, 60 miles from the capital Bangkok. She was then detained and paraded at a police press conference alongside General Surachate Hakparn, deputy commander of the country's police force.

Speaking at the police event, she said: 'I knew. I knew after [the accident]. When I saw the guy's body condition, I knew at that moment that he was definitely dead.

'Can I not answer more about this, because it is something that makes me uncomfortable.'

She said that because it was winter, the roads were dark, and as 'normally nobody walks' at that time 'she thought she had ran into a deer'.

Tubtim said she was 'shocked when she realised it was a person'. She said that after the crash, she did not go down to help but wanted to wait for 'someone else of the police to arrive there first'.

She added: 'Because my sister who lives in the UK just returned to Thailand has bought a house for her daughter, I thought of going back and talking to her.

'I wanted to talk with her about it and see what I should do. I don't normally see her, my sister lives in the UK and just came back here to Thailand. So I searched for a flight ticket back to Thailand.'
