Police quiz suspect

A man suspected of carrying out an attack on a factory near Lyon in France in which a man was found decapitated continues to be questioned by police.

Yassin Salhi, 35, caused an explosion by ramming his vehicle into an area containing flammable liquids, prosecutors say.

His boss, the owner of a delivery firm, was found beheaded alongside flags with Arabic inscriptions.

President Francois Hollande has held a security meeting with ministers.

Prime Minister Manuel Valls cut short his visit to South America to return to France which is on its highest state of alert after the attack in the small town of Saint-Quentin-Fallavier some 40km (25 miles) from Lyon.

Officials and residents of Saint-Quentin-Fallavier gathered outside the town hall yesterday morning to observe a minute's silence.

Salhi was arrested at the Air Products factory on Friday morning.

Later, anti-terror police searched the apartment of Salhi, a father-of-three, in the Moines neighbourhood of the town.

They took his wife and sister into custody. Another man was arrested but released without charge.

Agnes Thibault-Lecuivre, spokeswoman for the Paris prosecutor's office, has said police have so far not found any motive or possible foreign connection, and that Salhi is not speaking to investigators.

Yassin Salhi had been investigated in the past about his alleged links with Islamist militants.

It is alleged he was waved through the gates of the factory because he was a regular delivery driver.

Salhi's boss, a 54-year-old man whose name has not been released by police, was found beheaded at the scene.

His head had been placed on the factory railings. It is not clear when he died.
