Prince Edward Island RCMP have arrested Seyed Amir Hossein Raisolsadat under a section of the Criminal Code related to terrorism.

RCMP said Raisolsadat, 20, of Stratford, P.E.I., was arrested Tuesday under Section 810.01 of the Criminal Code, which says police may pursue an application for an order to keep the peace if they have reasonable grounds to believe that a person may commit a terrorism-related offence.

Police gave no specific details and made no mention of any charges pending against Raisolsadat.

He was released from RCMP custody on $500 bail under the conditions that he remain in P.E.I. and not possess firearms.

He must also report to police once a week.

Raisolsadat will return to court on April 20.

CBC News was not able to reach Raisolsadat Wednesday for comment.

Whatever concerns the RCMP have with Raisolsadat are allegations at this point and have not been proven in court.

'Normal university boy'

Neighbours say the family moved into their home in a residential neighbourhood of Stratford late last year.

"They moved in around November. A mother and two university-age sons, as far as I know. Very normal university boy behaviour. Had friends over. Got picked up by friends. Got dropped off by friends," said neighbour Amy Scales.

"I offer my sincere gratitude and respect to the members of the P.E.I. RCMP L Division for their diligent and effective efforts that led to yesterday's terrorism-related arrest in Charlottetown," said P.E.I. Attorney General and Justice Minister Janice Sherry said in a statement.

"As Islanders, and Canadians, we share comfort and pride in the work the RCMP carries out in response to activities that may be a potential threat to the safety of our communities."

In the House of Commons Wednesday afternoon, the Minister of Public Safety Steven Blaney also thanked the RCMP for their work on this case and others.

"It is clear that terrorism remains a real threat to Canadians. That's why we've tabled the Anti-terrorism Act, 2015," said Blaney.

Bill C-51, Canada's new anti-terror legislation, introduced in January, would give police much broader powers and allow them to detain terror suspects. It would also give new powers to Canadian Security Intelligence Service (CSIS).
