Knifeman who tried to kill Army officer after researching Lee Rigby murder is jailed

A knifeman who tried to kill a uniformed Army officer in an ambush outside his barracks has been jailed for life.

Anthony Esan, 25, repeatedly stabbed Lieutenant Colonel Mark Teeton using two 10-inch knives in Sally Port Gardens, near Brompton Barracks, Chatham, on July 23, 2024.

He bought blades from Argos only days earlier and had made a series of chilling internet searches, including ‘Woolwich soldier murdered’, referencing the killing of fusilier Lee Rigby a decade earlier.

Lt Col Teeton’s wife Eileen Teeton bravely rushed to the scene outside the family home to a soldier lying on the ground.

In her victim impact statement, she said: ‘I watched horrified by his continued savage attack, and realised it was my husband on the ground and he was carving at his face and neck.’

Mrs Teeton described visiting her husband in hospital, when he asked, ‘Do the people at work know what he tried to do to me?’, before adding: ‘Cut my head off! Like Lee Rigby.’

Prosecutors said Lt Col Teeton, a chief instructor at the British Army’s Royal School of Military Engineering, was targeted in a ‘vicious and deliberate’ attack because of his appearance as a soldier.

But a four-day sentencing heard that experts agree Esan had schizophrenia at the time.

Forensic psychiatrists told the court it is more likely that Esan set out to stab a soldier but that the main driver of his actions was psychosis.

He has been receiving treatment in Broadmoor Hospital, but the court heard Esan remains psychotic and will have to be treated for the rest of his life.

Judge Mr Justice Picken said: ‘The attack on Mr Teeton was targeted and deliberate.

‘You were looking for a soldier with the intention that that soldier should die, as underlined by the fact you had looked up the killing of Lee Rigby on the internet.’

Esan previously admitted attempted murder and possessing two bladed weapons.

He was handed a minimum term of seven years and 162 days – but will be detained at Broadmoor high-security psychiatric hospital, where he has been receiving treatment, for as long as necessary.

The judge said: ‘The psychotic disorder is part of the context for the attack but it is not the entire context, since the context also includes the fact that you targeted Mr Teeton, and that you did so having carried out searches in relation to other knife attacks, including most notably the killing of Lee Rigby, another soldier.’

He said the grudge that Esan held towards the Army worked in tandem, or in combination, with his psychosis.

Mr Justice Picken told Esan he presents a ‘significant risk’ to the public, adding: ‘You are unlikely ever to be released back into the community where there is a risk of reoccurrence.’

Following his sentencing, the judge said he wanted to commend everyone who came to Lt Col Teeton’s assistance, in particular his wife Eileen Teeton, and praised them both for their ‘immense courage’.

Footage shown to the court showed the moments Esan parks up his moped and stops Lt Col Teeton walking home from the barracks at 5.53pm.

He asked the father-of-two if he could use his phone because his moped had broken down and he needed to call someone to come and help, before beginning his attack.

More footage from a car showed the attack in the middle of the road with Esan stabbing Lt Col Teeton, who gets up and walks the other way, and Esan going after him and continuing his attack.

Lt Col Teeton, a serving officer in the British Army for 26 years who has been on two tours in Iraq and two tours in Afghanistan, tearfully told the court of being ‘forever in gratitude’ to the ‘heroes’, including his wife Eileen, who came to his aid that day.

‘I still relive the incident in my mind; I actually think it is a blessing that I was unconscious for much of it as it means that I am unable to remember a large part of being attacked,’ he said.

‘I don’t think I will truly appreciate the courage shown by my wife and strangers to thwart the attack and then the quick thinking of an array of people that helped save my life.’

Lt Col Teeton said he was told by medical staff it was a ‘miracle’ that he survived the attack having been left with a very large wound to the right side of his neck and further stab wounds to the front and back of his chest, front and back of his abdomen, left side of his lower abdomen, right groin, right upper arm and left thigh.

He added: ‘I did not imagine for a moment that I would be attacked in such a way on the streets of Britain, in a place where I felt safe.’

Esan was born in Nigeria and moved to the UK in 2009 and lived in the Southwark area of London before the family relocated to Kent in 2022.

The court heard that Esan had made several unsuccessful attempts to join the British Army in the years before his attack, with his first application in 2020.

That same year, he had been referred to mental health services as he appeared to be mentally unwell and reported hearing voices.

The court heard that in January 2023, Esan’s mother had contacted an out-of-hours service concerned that he had knives in his bag.

Expert witness in forensic psychiatry Professor Nigel Blackwood said that when he brought knives back to the family home, that Esan ‘began to entertain murderous fantasies 18 months before he enacted them’.

Prosecutor Alison Morgan KC had also said Esan had an ‘interest’ in knives, with packaging for two ‘Rambo’ knives later to be recovered from his bedroom.

Since the middle of last year Esan said he felt he was in the film Kingsman, which Ms Morgan described as ‘profoundly violent’ and a video game called Cyberpunk.

He believed his role was to ‘deliver and shoot’, the court heard.

Esan has been receiving treatment in Broadmoor Hospital, but Prof Blackwood said he remains psychotic and will have to be treated for the rest of his life.
