Jordi Antunes-Barros, 18, was in Montreal court on four charges today after police found homemade explosive devices in his family’s home in Ahunstic-Cartierville.

Antunes-Barros was charged with possession of incendiary material, possession of a weapon for dangerous purpose, using explosives and possession without lawful excuse.

The court has ordered that he undergo a psychiatric evaluation at the Pinel Institute before moving forward.

Defence lawyer Valerie Rivest said Antunes-Barros suffers from Asperger's Syndrome, but more tests are necessary.

"He was diagnosed last year but there was nothing else that was discovered. But that's why we want him to go to Pinel — to know exactly what's happening for his mental disorder, if he has one or not," Rivest said.

Antunes-Barros was arrested on Saturday after police received a tip about him storing over a dozen explosive devices in the family home.

Police began their operation on Robertine Barry Street, near Alice Nolin Street in Ahuntsic-Cartierville, and evacuated several homes in the area as a precaution.

Specialists with the Montreal police used a bomb-defusing robot in the 15-hour operation.

They found 19 homemade explosive devices.

No one was injured.

Antunes-Barros is due back in court on June 23.
