A teenager on trial for attempted murder who plunged a samurai sword into a man's back has told a jury there was "no intention to kill" him. 

The 16-year-old boy, who cannot be named for legal reasons, told jurors that he had gone to get the sword for "self-defence" against two people who he claims had a crowbar. 

Giving evidence, the boy said he got out of a car near Daisy Dip on Laburnum Road, Southampton, and that his victim, Ben Glasspool, "chucked" the crowbar away. 

He then agreed that he ran up to him and "immediately started to hit him with the sword".

Southampton Crown Court previously heard how Mr Glasspool had gone to the area amid a dispute but suffered a "massive wound" after the 16-year-old climbed out of a Ford car driven by a woman and set upon him with the sword.

He was taken to hospital with the weapon having sliced through three of his ribs and punctured his lung, prosecutor Charles Gabb said.

The boy denies attempted murder but has previously admitted wounding with intent. 

Giving evidence, the boy said: "All I remember is I hit him a few times in the legs, I must have hit him in the arms.

"He was in front of the car. I went around and he tried running away and that is when I hit him in the back."

The jury previously heard the samurai sword had become stuck in Mr Glasspool's body and had to be pulled out. 

But the boy said: "I didn't yank anything out of the body."

He added: "I just swang the sword randomly. I didn’t know at the time that it could do that much damage to someone."

When asked by Judge Christopher Parker what he was attempting to do, the boy said: "Obviously like hurt him a little bit but there wasn't intention to kill."

He said the sword was bought for him and that it was going to be put on his bedroom wall as an ornament. 

Asked why he went to get the sword, he said: "I just thought it would scare them off a bit."

He said: "I didn’t want to kill him," and added that he wanted to "whack them a little bit with it... obviously hurt them a little bit with it". 

But the prosecutor said this was a "revenge attack" adding that he had been "wielding that sword like a baseball bat".

Both the woman driver - Nicola Kayley, 45, of Bluebell Road, Southampton - and an older boy - have admitted offences over the incident, the jury was told.

The trial continues.
