KNOWN WOLVES:

More from the Daily Mail:

One of the terrorists, a 19-year-old Frenchman who lived close to the church, is said to have left for Syria in 2015 to try and join Islamic State, but he was arrested.

He was jailed for terrorist offences following a short trial in France, before being released on March 2 this year.

The Tribune de Geneve reports he tried travelling to Syria via Turkey, but was kicked out of the country and arrested at Geneva airport on May 14 last year.

It was the second time he tried to reach Syria, the first time via Munich unsuccessfully, before he tried through Switzerland.

He was jailed for a few days in in the prison of Champ-Dollon before being extradited to France and convicted of conspiracy to prepare acts of terrorism.

His conditions included returning to live with his parents, wearing an electronic tag, and reporting to his local police station.

But this did not stop him becoming involved in today’s atrocity, in which Father Jacques Hamel, 86, had his throat cut.

According to his bail conditions, the electronically tagged terrorist was allowed out unsupervised between 8.30am and 12.30pm.

Unsupervised?
