George Zimmerman 'found with bloody nose'

A Florida neighbourhood watch volunteer who shot an unarmed black teenager had a bloody nose and a cut on his head, according to police reports.

The documents were released to defence lawyers for George Zimmerman, who is accused of second-degree murder over the 26 February killing in Sanford. He has pleaded not guilty.

The evidence includes a post-mortem examination that found traces of cannabis in Trayvon Martin, who died in the confrontation.

Mr Zimmerman, 28, maintains he shot the 17-year-old in self-defence.
