French police foil Paris bomb attack outside US bank
The incident occurred around 3:30 am (0130 GMT) in front of a Bank of America building in the chic 8th arrondissement, a couple of streets from the Champs-Elysees.
Police grabbed the suspect just after he placed a device, made of five litres of liquid (1.3 US gallons), believed to be fuel, and an ignition system, one of the sources said.
After his arrest, the suspect claimed to both a minor and a Senegalese citizen, according to a police source, who cautioned that the authorities were still verifying his identity.
