Prosecutors will call more witnesses Friday in the trial for Officer Edward Nero, one of the Baltimore police officers facing charges stemming from Freddie Gray's arrest and subsequent death.

Gray died April 19 of last year, a week after his neck was broken while he was handcuffed and shackled but not seat-belted into the back of a police van.

Nero faces assault, misconduct in office and reckless endangerment charges stemming from Gray's arrest. Prosecutors say Nero and two other officers arrested him illegally, and that they were negligent by failing to buckle him into a seat belt. Nero's attorney said Nero didn't arrest the man, and that it was the wagon driver's responsibility to secure Gray. His trial began Thursday.

Nero is one of six officers charged in the case.
