The fourth man arrested in the police investigation into an alleged Ottawa-based terrorism cell made another court appearance Sunday.

The 20-year-old man, who was born in Iraq and is a Canadian citizen, was arrested Friday morning in Ottawa on his way to work but not charged with any terrorism-related offences. Instead, police laid unrelated charges involving alleged domestic assault.

A justice of the peace granted him bail Saturday, but 10 minutes later he was arrested again on similar charges. Again, the charges were not related to any terrorism offences.

In Sunday's court appearance, the man's case was adjourned until Tuesday for another bail hearing.

The man's lawyer, Richard Morris, said his client is frustrated at the round of charges and wonders whether they are only being brought to further the RCMP's investigation into the alleged terrorism plot.

Morris said the young man is depressed and unable to eat. The lawyer added that up until now, his client has never had any contact with police.

'Never been in any trouble'

"He's never been in any trouble before in his life," Morris told reporters. "He's never had any contacts or dealings with the police that I'm aware of, and he finds himself taken down on his way to work on Friday morning."

After his initial arrest, the man was interrogated for several hours, Morris said.

Michel Juneau-Katsuya, formerly with CSIS and the RCMP, speculated the police may be trying to gain some time while the man remains in detention. "They are trying to save time somewhere in order to have something for the right moment — either the right judge or the right amount of evidence."

The RCMP earlier issued a media release stating the man is a focus of its terrorism investigation.

Three Ontario men are facing charges in the case after being arrested last week.

Hiva Mohammad Alizadeh, 30, and Misbahuddin Ahmed, 26, both of Ottawa, and Khurram Syed Sher, 28, of London, Ont., are accused of conspiring to facilitate terrorism with others in Canada, Afghanistan, Iran, Pakistan and Dubai over the past two years. Those three men will be in court Wednesday.
