Trayvon Martin: Florida police chief steps down

A Florida police chief, who has been criticised over the investigation into the shooting of an unarmed black teenager, has announced he will temporarily step down.

There has been widespread community anger since the death of 17-year-old Trayvon Martin in February.

The head of police in the city of Sanford, Bill Lee, says he's become a distraction.

He was criticised for not arresting a man called George Zimmerman, a member of a neighbourhood watch group, for the shooting.
