The lawyer for the family of an unarmed US black teenager killed by a neighbourhood watch volunteer has called for the man’s arrest.
Trayvon Martin, 17, was killed by George Zimmerman, 28, while walking through a gated community in a suburb of Orlando, Florida.
Mr Zimmerman says he was acting in self-defence.
The US Department of Justice has announced an investigation into the police handling of the case.
A Florida grand jury will also hear evidence in the case on 10 April, a state prosecutor has said.
