Trayvon Martin was suspended from school three times in the months before he was shot dead by a neighborhood watchman, it emerged today.

The new claims, revealed in a leaked report, paint a different picture of a teenager who frequently found himself in trouble with authorities.

It was also revealed that he might have attacked a bus driver, according to a Twitter account that it is claimed belonged to the teen.

The Miami Herald claims that in October, he was caught with a 'burglary tool' - a flathead screwdriver - and 12 pieces of women's jewellery. Martin insisted that they did not belong to him.

Earlier, he had been suspended for skipping school and showing up late to class. And most recently, in February, he was suspended again when officials found a 'marijuana pipe' and an empty baggie with traces of the drug.
