London community seeks answers about 4th Canadian

Residents in London, Ont., are seeking answers about Ryan Enderi, also known as Mujahid, a Libyan-Canadian who may be may be connected to the deadly attack on an Algerian gas plant.

CBC News identified Enderi last week as the fourth Canadian man under investigation related to the brazen January attack, when militants linked to al-Queda killed dozens of workers at a gas plant in Alergia.

Enderi is believed to have travelled overseas around the same time as three other young men from the same London, Ont., community. Ali Medlej and Xristos Katsiroubas were among the dead at the gas plant, while the other man, Aaron Yoon, is currently in a Mauritania jail.

People in the community told CBC News that Enderi left London in 2010 to go to Libya, presumably to operate an importing business that was being run by his father, Abdul, who bought and sold used vehicles. They said that Abdul joined his son three months ago and that both are alive and well in Libya, although their whereabout remain unconfirmed.

Abdul and Ryan Enderi attended prayers at a local mosque and reportedly adhered to an ultraconservative sect of Islam.

CBC News visited the Enderi home, but residents did not respond.

John Krogman, a neighbour of the Enderis, said that the family was quiet, respectful, friendly and kept to themselves. He said that the elder Endari had been an architect but was on social assistance for several years.

Members of a local church said if Ryan was indeed involved in the Algeria attack, someone in the household would have known, and they are asking anyone with information to come forward.

"That was the message, that if anyone out there knows — in the community-at-large, in the Muslim community-at-large as well — to raise the alarm, to speak out so that people in the community get a sense of what is going on," said CBC reporter Ioana Roumeliotis.

"There's a real concern that these young men were recruited somehow, were radicalized -- and potentially [by] someone in London," she added.
