Three Detroiters were among seven people arrested in Ferguson, Missouri early Friday, according to NBC News.
The protests are linked to the police shooting death of unarmed teen Michael Brown.
NBC News reports Missouri Highway Patrol Capt. Ron Johnson said early Friday that three of those arrested were from Detroit and the rest from the St. Louis area.
One person was arrested for an outstanding warrant, one for driving through a police checkpoint and the rest for failure to disperse under orders, Johnson said.
Thursday marked a second night of calm in the St. Louis suburb, with a group of less than 100 protesters.
Missouri Gov. Jay Nixon ordered the National Guard to begin pulling out of Ferguson earlier Thursday, saying "the situation has greatly improved."
