STOCKHOLM, Sweden (AP) _ Two men were found dead in the wheel bay of a jetliner at Stockholm's Arlanda international airport, police said Monday.

Technicians performing a routine check on Sunday found the apparent stowaways in one of the wheel bays, airport police spokesman Anders Nilsson said. The cause of death was not released pending autopsies, but Nilsson said it gets very cold in the plane's undercarriage, where the atmosphere is not controlled

The Premiair charter plane had landed in Stockholm earlier Sunday after a trip to Greece, but police said it was not clear how long the men had been hidden in the undercarriage.

Identity documents suggested that they came from the Dominican Republic, where the Airbus A300 touched down Friday, but police said the identities were still under investigation.
