9 youths charged after robbery shared on Facebook

Police in Baltimore have arrested nine young people after a video shared on Facebook allegedly shows them with a man whose cell phone had just been stolen.

The victim of that theft can be seen on the video asking the teenagers for his phone back.

Police spokesman T. J. Smith said at a news conference Wednesday that the group - both boys and girls, from 12 to 18 years old - was arrested Tuesday after a second assault several blocks away.

Smith says police believe some in the group also are responsible for a string of assaults last month.
