Trayvon Martin may have attacked a Neighborhood Watch captain before the man shot dead the unarmed teen in a gated community in Florida, an anonymous witness who spoke to police claimed yesterday.

The witness, known only as John, told Sanford police that he saw Martin on top of George Zimmerman shortly before the fatal shot that has led to a national outcry, including a huge ‘hoodie’ march in Philadelphia last night.

He recounted the details to Fox 35 News in Florida.
