A Michigan man asked two people whether they were Muslims at a bus stop before stabbing them repeatedly Saturday, the victims told police.

Terrence Lavaron Thomas, 39, stabbed a 52-year-old Detroit man five times and another 51-year-old Detroit man who tried to intervene during the first stabbing, the Detroit Free Press reports.

Police arrested Thomas a couple of blocks away from the incident. He was carrying two knives and marijuana and told police he was a Muslim, Southfield, Mich. Police Department says.

Thomas was arraigned Tuesday on two counts of assault with intent to murder, once count of carrying a dangerous weapon with unlawful intent and possession of a controlled substance.

The FBI is investigating whether the incident violated hate-crime laws, according to a statement from the police department.

An investigation could lead to federal charges if ethnic intimidation was a factor in the stabbing, the paper says.
