A VIOLENT thug could find out his true parentage through a DNA test - when he is sentenced for carrying out a hammer attack on his dad.

Amandeep Johal, of Hogg Lane, Grays, admitted wounding with intent to cause grievous bodily harm and possession of an offensive weapon after carrying out the sickening street attack in Maidstone Road, Grays, on September 9.

Basildon Crown Court heard the 22-year-old struck his father Amarjit on the head, body and wrist after he said to him: “I’m not your father and there’s nothing you can do about it.”

David Hewitt, mitigating, told the court there was a “sensitive” family history and tensions leading up to the incident.

He said: “Mr Johal says that he saw the victim walking down the road away from him. The victim turns around and starts walking back towards him.

“An argument ensues and there is a complicated history surrounding this.

“At this point, the victim said: ‘I am not your father and there is nothing you can do about it.’

“The victim says in his statement that he is the father. He turned to run off and my client saw the hammer laying on the floor.

“He ran after the victim and hit him with the hammer a number of times.”

The court heard a DNA sample was taken from Amarjit Johal as part of the prosecution case and could now be used to find out the truth, despite the fact that a trial is not needed.

Mr Hewitt said: “The victim in his statement says he is the father. There is a real possibility that the DNA should be looked at by experts.”

However, David Blackburn, prosecuting, said the victim would need to be consulted.

He said: “As relates to the sample taken from the complainant in this case, if it relates to a relevant matter between the Crown and the defence then there could be grounds for that.

“But the issue of the DNA test is simply of no relevance to sentencing.

“There is also an argument to say that there is an intrusion into the private life of the person who the sample has been taken from.

“It’s his DNA after all.”

Judge John Lodge declined to make a ruling on the issue but said he would consider all the facts when he passes sentence on February 6.

He said: “I can say for my part that when looking at the background of a very serious attack by a child on a parent that all the relevant matters need to be investigated.”
