A Mississauga man says he was treated like a terrorist when he was stopped at gunpoint and held for six hours at the Windsor-Detroit border in a case of mistaken identity.

Ayaz Bangash says he was on his way to Chicago to celebrate Eid with his sister on Wednesday when border officers, guns drawn, suddenly surrounded his car.

Bangash says he shares the same last name, country and month of birth as a man allegedly on a wanted list, and he fears the repercussions of the coincidence will continue to haunt him.

“I’ve been harassed and treated as a terrorist,” he said. “I feel insecure. If the bad guy does something wrong, then what?”

It is not known whether the list is American, Canadian or international. Neither Canada nor the U.S. could confirm that information.

Bangash, a Canadian citizen, says he’s stopped every time he travels and it’s been happening since he arrived in Canada from Pakistan in 2007. Wednesday was his first attempt ever to get into the U.S.

He says that immediately after his passport was scanned, five police officers with their guns out surrounded his car, shouting at him to get out and put his hands up.

He was then handcuffed and detained for six hours.

The U.S. Customs and Border Protection Office of Field Operations could not confirm the incident, citing U.S. privacy laws.

Bangash says officers took all his belongings, including his wallet and phone. They also took a diary he keeps in his car which includes all his passwords for digital sites, including his bank. The items have been returned but Bangash is worried that his sensitive information has been compromised, so he’s changing all his passwords.

During his detention, he was asked several questions such as where he was born, where he studied, how many kids he has, and how and why he was in Canada. Bangash says he answered all questions.

“I respect the law wherever I am,” he explained to CityNews. But he thinks the U.S. officials went too far.

“This should not be happening,” he said. “They should just simply ask questions and explain what’s happening.”

At the end of the six hours, an officer told him he’s “inadmissible” to the U.S. and wouldn’t tell him why.

“They said they had good news and bad news. The good news was I wasn’t the same person they were looking for and the bad news was that I was not admissible to the U.S.”

An officer apologized and told Bangash that they were after a “real bad guy.”

“If you were handcuffed on Christmas, how would you feel?,” Bangash asked the officer.

The officer replied saying the incident would never happen again.

But it did happen again, just moments later.

Bangash says he was asked to follow a police car back to the Canadian side of the border.

But shortly after beginning to drive, he says another officer ordered him out of his car and handcuffed him.

He was then driven to the Canadian side where he was finally released.

“Every country is sovereign and able to make its own decisions about admissibility,” Scott Bardsley, Press Secretary for the Office of the Minister of Public Safety and Emergency Preparedness said. “Questions about how the United States makes admissibility decisions are best directed to US Customs and Border Protection.”

In 2011, Bangash was granted a visa to visit the U.S. which was later cancelled with no reason given.

Similar questioning has happened in Canada, he explained, earlier this year at Pearson Airport on his way to Pakistan for his father’s funeral.

Immigration lawyer, Guidy Mamann, told CityNews border police have every right to detain and question a person, without much explanation.

“They have no obligation to tell you (why),” he said. “You have no right to counsel, they have the absolute right to ask you any kinds of questions that they want and detain you as long as they want and make decisions which are really not subject to appeal.”
