Baltimore police have arrested more than 60 people during a protest after participants blocked lanes on an interstate in the city.

The numbers were initially around 20, but police spokesman Lt. Jarron Jackson later updated the figures to 55 adults and 10 juveniles arrested when protesters blocked traffic on Interstate 83 on Saturday. He said the charges will be failure to obey and illegally walking on a highway.

Social media video showed people forming a double line with their arms linked across the road. One participant wore a shirt referring to Freddie Gray, the man who was fatally injured in police custody.

Organizers say they want a civilian review board created for police investigations. They also want 10 percent of the city's police budget reallocated for community programs.
