A woman in her forties was killed in the Paris metro after her coat got stuck in a door while she was getting off the train, the Paris independent transport authority and the public prosecutor said Sunday.

"Shortly at 16:00 in the Bel-Air metro station, the coat of a woman born in 1977 got stuck when she got off the train, killing her," the Public Prosecutor's Office said. According to the media, she got out of the carriage quickly and was pulled by the train when it started again.

An investigation was opened into the cause of death.

"The driver was in shock and was taken care of by his management and ambulance personnel," the Paris independent transport authority said, adding that "a victim assistance cell was launched immediately."
