After a mistrial was declared in the first trial over Freddie Gray's death, lawyers on both sides met with the judge Thursday to discuss a possible retrial but did not set a date, according to a court spokesperson.

Circuit Judge Barry Williams on Wednesday declared a mistrial in police Officer William Porter's case. Jurors had reported that they were deadlocked.

Porter is one of six officers charged in Gray's death. Gray's neck was broken in the back of a police transport van in April. His trial lasted a little more than two weeks.

The jury took three days to deliberate on the charges of manslaughter, assault, reckless endangerment and misconduct in office.

Also Thursday, a protester whom officers had arrested outside the courthouse the previous day was released.

21-year-old Darius Rosebrough, an activist also known as Kwame Rose, said by phone Thursday that he was released around 3:45 a.m. A 16-year-old juvenile was also arrested, but it isn't known if he has been released.

Maj. Sabrina Tapp-Harper, a spokeswoman for the Baltimore Sheriff's Office, said both were charged with disorderly conduct, failure to obey a law enforcement officer's command, and disturbing the peace by using a bullhorn outside the courthouse while court was in session.
