A 15 year-old boy has attacked a burglar with a samurai sword after a bungled attempt to steal his PlayStation 3.

Damian Fernandez and his sister Deanne were at home alone when two burglars entered their house in Miami. They took some household items, and began to search for the console after spotting an empty PS3 box.

While his sister hid in the closet Fernandez, a brown belt in karate, decided to attack.

"I jumped off my (bunk) bed and I grabbed my sword ... and I just waited for him," he told Local10.com.

Fernandez lunged at the burglar with his samurai sword, striking him in the chest. "He freaked out," Fernandez said.

The 15 year-old then chased the burglar down the street while his sister called the police. A police dog found the burglar hiding behind a bush in a nearby house.

Javier Cotera was arrested and released early the next morning on bond.
