PARIS — French police have thwarted a suspected bomb attack outside a Bank of America building in Paris, authorities said Saturday. One suspect was detained and another escaped.

The national anti-terrorism prosecutor’s office, or PNAT, told The Associated Press that it has opened an investigation into alleged terrorism-related offenses.

The suspected offenses include attempted damage by fire or by a dangerous means, the manufacture of an incendiary or explosive device, the possession and transport of such devices with the intent to prepare dangerous damage and involvement in a terrorist criminal association.

A person was placed in police custody.

“Well done to the rapid intervention of a Paris police prefecture unit, which made it possible to thwart a violent act of a terrorist nature overnight in Paris,” Interior Minister Laurent Nuñez said.

“Vigilance remains at a very high level,” Nuñez said.
