Salah Abdeslam
The 26-year-old French national born in Brussels has been identified as a key suspect, and he is the subject of a massive police manhunt in Belgium and beyond. He is described as dangerous, and police have warned the public not to approach him.
He is believed to have rented a VW Polo car in Belgium, which was later found near the Bataclan concert hall where 89 people were killed. But he also rented a Renault Clio and reserved two hotel rooms outside Paris before the attacks.
His precise role in the attacks themselves is unclear, although his brother Brahim blew himself up.
Investigators believe Salah Abdeslam may have driven the three Stade de France bombers to their destination and may have been given the job of an attack a short distance south, in the 18th district. That attack never happened.
