The Wall Street Journal reported Saturday that at least one of the attackers responsible for Friday night’s terrorism in Paris tried to enter the France-Germany soccer game at Stade de France with a ticket.

A security guard at the stadium — identified only by his first name, Zouheir — told the WSJ’s Joshua Robinson and Inti Landauro that the attacker was discovered to be wearing an explosive vest when he was frisked at the entrance about 15 minutes after Friday night’s game began.

Here’s the WSJ with more:

While attempting to back away from security, Zouheir said, the attacker detonated the vest. Zouheir, who was stationed by the players’ tunnel, said he was briefed on the sequence by the security frisking team at the gate.
A police officer confirmed the sequence, adding that police suspect the attacker aimed to detonate his vest inside the stadium in order to provoke a deadly stampede.

That blast, along with another outside the stadium about three minutes later that happened when a second person blew himself up, were clearly heard inside the stadium during the game. One non-terrorist died in the stadium blasts.

France President Francois Hollande was in attendance at the game. He was rushed from the stadium after the blasts.
