Trayvon Martin: CCTV shows George Zimmerman after shooting

Images have emerged of Florida neighbourhood watch volunteer George Zimmerman arriving at the Sanford Police Department.

The man who says he shot unarmed black teenager Trayvon Martin in self-defence steps out of a police car before being led inside by police officers. The video was recorded minutes after the fatal shooting took place.

US media have speculated that Mr Zimmerman appears to be clean and shows few signs of having been attacked, as his police statement claims. He seems slimmer than in a 2005 mug shot circulated since the shooting.

The footage is the first image of Mr Zimmerman to be released since the incident took place on 26 February. The video was acquired exclusively by ABC News.
