A Canadian man who vanished last year while travelling in a truck with a crew of other men has been found safe in Turkey, authorities said on Wednesday.
Police had said the truck was going southbound on a highway in the southeastern province of Diyarbakir when it hit a tree and caught fire.
It was one of three vehicles that crashed into a tree on a motorway near the town of Mardin, a police official told AFP news agency.
The third vehicle, which was travelling southbound, was also found in the accident, according to the official.
He said the men who had been arrested earlier in the day were all foreign nationals.
The truck was registered in the name of a Canadian citizen who was travelling to Turkey for medical treatment, the official said.
The official said the three men were from Alberta and Saskatchewan, as well as Quebec and New Brunswick.
The Canadian government has been struggling to find the missing men, including one who was found dead in a lake near the provincial capital, Ankara, last year.
