A man who bought his first mobile phone at the age of 49 has received a flood of abusive calls.

Junior Guy, of Orlando in Florida, says the calls started as soon as he switched his phone on. Strangers called at all hours. Some were insulting. Others angry. Sometimes, they threatened him.

Killed ... Trayvon Martin.

By the second day he figured out what was going on.

The phone company had given him the number previously used by George Zimmerman, a neighbourhood watch volunteer who caused a storm when he shot a young man dead in February.
