On Thursday, May 18, 2018, Samiualahq Akbari, 32, of Brigstock Road, Thornton Heath, was sitting on a bridge above Westmayne in Laindon and threw concrete blocks into the windscreen of a lorry and three vehicles.
He also shouted threats at the drivers as they passed.
Essex Police attended the scene and chased Akbari, who is also known as Sami Ul-Haq. He was found in an undergrowth and was arrested.
The road was closed while officers dealt with the aftermath of Akbari's actions, which included pulling a concrete post out of one lorry.
In a separate incident in London the dangerous individual drunkenly looked for someone to harm after calling his cousin and telling him he wanted to 'kill English people'.
Akbari appeared at the Old Bailey on Wednesday (August 14) where he received four years in jail for four counts of criminal damage with intent to endanger life.
However, for the incident in London, he was jailed for 21 years for attempted murder.

After the phone call in which Akbari said he wanted to 'kill English people' his concerned cousin travelled to Thornton Heath to check on him. They both went to a fast food shop and while Akbari was inside his cousin contacted police.
When his cousin tried to persuade him to go home, Akbari ran off and officers met the cousin nearby.
A search began to trace Akbari’s whereabouts but he had entered a kebab shop on London Road and approached two customers asking them were they were from.
When they didn’t answer, Akbari walked behind the counter and took a large kitchen knife which he waved in a customer’s face.
He left the kebab shop with the knife and entered Plough-On-The-Pond Public House in search of further victims.
After asking customers in the pub where they were from he again lunged towards a group with the knife. The group were able to defend themselves so Akbari backed off and left the pub.
Afterwards the 32-year-old went into Tesco and approached a customer. He asked the victim where he was from and when he found out he was from the UK he charged at the victim with the knife.
The victim managed to jump backwards and the knife missed him, after a brief struggle, Akbari left the shop still carrying the knife.
Officers arrived at Tesco shortly after and spotted Akbari nearby, he ran off and was detained in a residential garden.
"Akbari is clearly a dangerous man"
Investigating officer, Detective Sergeant Nicholas May, of Basildon CID, said: "Every driver was very fortunate to not have been seriously injured, even killed by Akbari's actions.
"Each piece of concrete landed in the passenger side and it was coincidence that none of the vehicles involved had a passenger in it.
"It must have been a very concerning incident for all those involved and I thank them for their support."Akbari is clearly a dangerous man and he has been sent to prison for a significant amount of time for his actions."
