Cherif Chekatt, 29, is the suspected gunman who killed three and injured another 13 during a shooting in Strasbourg on Tuesday, the prosecutor's office told ABC News.
A helicopter was used to locate and identify Chekatt while he was on a public street, French Interior Minister Christophe Castaner told reporters. When a law enforcement agent approached him, Chekatt turned around and started shooting, Castaner said.
Police officers then engaged and "neutralized" him, Castaner said.
Chekatt, who was born in Strasbourg, allegedly shouted "God is great" in Arabic as he opened fire at the market, French prosecutor Rémy Heitz said during a press conference on Wednesday
He was on France's security watch list and had more than two dozen previous convictions for petty crimes in France, Germany and Switzerland, Heitz said.
Five people had been arrested in connection with the investigation into the shooting, near the Christmas market in the center of the city, a spokesperson for the Paris prosecutor's office told ABC News on Thursday.
The fifth detainee, arrested Thursday morning, was allegedly part of Chekatt's "entourage," according to the prosecutor's office. The other four arrested were Chekatt's's parents and two of his brothers, the spokesperson said.
The shooting, considered a terror attack by officials, sparked a massive manhunt for Chekatt and prompted government officials to establish more security around France's borders.
Members of the French military confronted Chekatt after he carried out the rampage, but he was able to flee the scene by jumping into a taxi.
The Strasbourg Christmas market will reopen Friday at 11 a.m., Castaner said. Strasbourg Mayor Roland Ries told reporters that he was "happy" about the reopening of the market because it'll help residents return to life as normal.
