It was agreed with family and friends they would all meet and agree there would be no more issues between the pair.
But instead the teenager got out of the car with a sword and started swinging it around and threatening victims, the court heard.
Oh, well, that didn't go as planned!
The teenager, who can’t named as he is under 18, is on trial charged with a host of offences in connection with the incident which took place on March 25.
“The defendant led the group to Gardener Avenue, Corringham and he got out the car with a sword and flicked it at the man and cut his chin and cheek and it was quite a serious cut.
“He was singing (sic) the sword around, described as a samurai sword.
“He also hit the man, and a woman and a girl who suffered bruising and swelling to her face.
“He was described as being irate and also rattled and threatening the three victims, while asking the man where his knife was.
“The girl suffered a barrage of punches with about five to the body and one to her face. The man got back in his car and called the police and discovered he was bleeding heavily.”
What a lovely chap!
