A “MANIC and deranged” man who stabbed his mother 11 times in a drug-fuelled psychosis has been jailed.

Charlie Mann, 21, attacked his mum Emma at the family home in Haywards Heath after spending an evening taking mephedrone, cannabis and alcohol.

During the early-morning attack on December 29, 2013, he shouted: “This is the prophecy. I love you, but this is the prophecy.”

Mr Mann, who was 19 at the time of the attack, had a history of drug abuse but had never suffered a violent or psychotic episode.

Prosecutor Amy Packham, speaking at the Hove Crown Court hearing, said Mrs Mann made a 999 call from the bathroom at 6.20am, telling the operator: “My son’s just attacked me and stabbed me and he’s going mental downstairs with the knives."

Officers arrived at the house and found the property in darkness.

When they entered, Mr Mann, who was naked, approached them covered in blood and tried to climb out of a broken window.

He told officers: “I have stabbed her multiple times. I have killed her. I have stabbed my mum and I need to be punished for what I have done.”

Prosecutors said Mr Mann appeared “manic and deranged”. He told officers: “I am a paedophile. I do not want to live. Take me to the light. I can see the vampires.”

Mrs Mann, who mouthed: “I love you” to her son in court as he stood in the dock, suffered injuries to her back, head, neck and arms and needed surgery for punctured lungs.

Mr Mann also required hospital treatment for serious injuries and spent much of his time in hospital sedated before being transferred to a psychiatric unit.

As previously reported in The Argus it is believed the 21-year-old cut off his own penis in the attack.

He pleaded guilty to inflicting grievous bodily harm at a previous hearing on January 19 this year.

Judge David Rennie jailed Mann for 16 months and told him he could expect to be released on licence on or around April 7, as he had already served seven months on remand.

He said Mann’s behaviour had been ‘wholly out of character’ and caused by a ‘drug-induced psychosis’.

He added: “Many parents would find forgiving an act such as this almost impossible.

“If there is one lesson to be learned from this tragedy, it is that young people who take drugs or mix drugs of this sort could suffer a psychotic episode or an episode worse than your own.”
