A friend of Freddie Gray, the black man who died from injuries suffered in police custody, testified that an officer on trial in the death told him to leave as Gray was being arrested.

Brandon Ross, who also recorded cellphone video of Gray being loaded in the police van, testified at Lt. Brian Rice's manslaughter trial on Friday. Ross says he wanted to complain to a police supervisor as Gray was treated, but Rice told him to leave.

Rice is the fourth of six officers — three white and three black — to stand trial in Gray's death. Gray suffered a severe neck injury while in the back of a police van. Two were acquitted and proceedings for another ended in a mistrial.

Rice's bench trial will resume Monday.
