A man carrying a Canadian passport is suspected of causing a car crash in Thailand Friday morning that killed one Thai woman and sent 12 people to hospital.

According to Thai news outlets, Francois Joseph Giannini was seen entering a roundabout at high speed in a black Nissan. The Nissan crashed into the side of a bus, pushing it off the road and into a tree where it came to rest.

The accident occurred between 4 and 4:30 a.m. local time.

According to Thai police quoted in the Pattaya Daily News, three passengers from the bus were ejected from the vehicle during the accident and taken to hospital. Nine people who were not thrown off the bus were taken to hospital where one, a Thai woman, died of her injuries. Six of the 12 people were seriously injured, including the driver.

Witnesses told the news outlet that 46-year-old Giannini appeared

intoxicated as he walked around the scene of the accident.

Giannini was carrying a Canadian passport which indicated that he was born in Beirut and his passport was issued in Bangkok in 2007.

"We are aware of the detention of a Canadian citizen in Pattaya and we are offering consular assistance," said Canadian Foreign Affairs spokeswoman Lisa Monette.

She said she could offer any more details because of the privacy act.
