A man has been jailed for 20 years after stabbing another man in the head and slitting his throat during a “harrowing attack” in a busy street.

Tony Henry, 37, of Dagenham Avenue, Dagenham, was found guilty of attempted murder at Snaresbrook Crown Court today for viciously assaulting his 36-year-old victim in Parsloes Avenue,

The court heard how Henry stabbed the man in the back of the head and chest and sliced his throat twice in the busy Dagenham street – in the middle of the day – on August 8 last year.

The victim was treated at the Royal London Hospital for head, neck and facial injuries and remained there for nearly a month.

He has since been discharged but continues to suffer both psychologically and physically from the attack, police said.

Det Con Elena Midlane, from Barking and Dagenham CID, called the attack “heinous” and noted that perpetrator has still not expressed regret.

“Tony Henry is a violent and volatile man who will now spend a considerable period of time behind bars,” she said.

“Even to this day he has not shown remorse and, following Henry’s not guilty plea, the victim was forced to attend court and relive the harrowing attack whilst giving evidence.

“He can now be assured that following a thorough investigation, justice has been served and this dangerous offender will no longer be a risk to the public.”

Henry was sentenced to 20 years in jail with a five-year extended license.
