French police pressed a massive hunt for two brothers suspected in the murderous attack on offices of the French satirical publication Charlie Hedbo after a teenager surrendered early Thursday.

Hamyd Mourad, 18, turned himself in to police after authorities identified the three men wanted in connection with the attack Wednesday that killed 10 journalists and two police officers. French police spokeswoman Agnès Thibault-Lecuivre said Mourad walked into a police station about 145 miles northeast of Paris and surrendered, according to The New York Times. “He introduced himself and was put in custody,” Thibault-Lecuivre told the newspaper.

Police were still looking for two brothers, Said Kouachi, 32, and Cherif Kouachi, 34. Both were said to be from the Paris region. Photos of the suspects were released, and police appealed to the public for help. One of the brothers has previously been tried on terrorism charges, Reuters reported.

The Associated Press said that Cherif Kouachi was tried in 2008 for helping funnel fighters to Iraq and sentenced to 18 months in prison. Kouachi told the court at the time that he was outraged by images that revealed the torture of Iraqi inmates by U.S. guards at the Abu Ghraib prison, according to the AP.

French media reported that police were seen searching a building in the city of Reims late on Tuesday. more
