Baltimore death sparks protests in New York, Boston

Hundreds of people rallied and marched in New York and Boston to protest the death of a Baltimore man who was critically injured in police custody as Philadelphia activists prepared for their own demonstration.

More than 100 people were arrested in New York on Wednesday night after police on a loudspeaker warned them they would be taken into custody if they marched in the street.

Police said most arrests were for disorderly conduct. Final figures were expected later on Thursday.
