MP for Dartford Gareth Johnson has blasted the "evil" and "cowardly" assailants who carried out Sunday night's heinous noxious substance assault in Keyes Road.

Officers from Kent Police were called to the street at approximately 3:40pm on February 3 to reports of the assault which sent three people to hospital.

It is alleged that said substance was thrown in the direction of a car by two men riding a motorcycle.

Kent Police have since confirmed that one man remains in hospital while the other two patients were discharged on the same day.

Speaking on the nature of the assault, Gareth Johnson MP has slammed the perpetrators and has promised that additional units will patrol the area to keep residents at ease.

"Assaults with noxious liquids are evil and anybody found to have carried out one can expect a lengthy sentence. Fortunately, this sort of incident is very rare in Dartford which makes it all the more shocking.

"I have spoken with Kent Police about this awful incident on Sunday and they are determined to fully investigate the circumstances behind this attack.

"In addition, there will be uniformed patrols across Temple Hill to help reassure local residents," he said.

According to the Acid Survivors Trust International, The UK has one the highest rates of recorded acid attacks in the world with 454 crimes involving corrosive substances occurring in London in 2016 alone.

The Trust also notes that this has become such a major problem due to the fact that the UK does not have tight controls on the sale of acid and doesn't have specific legislation when it comes to these types of attacks.

At the moment, it is illegal to carry sulphuric acid above 15 per cent concentration without a licence with those caught carrying such a strong substance now facing a two-year prison sentence and an unlimited fine.

This came after changes to the Poisons Act which now forces those wishing to purchase or import sulphuric acid above 15 per cent concentration to obtain a licence from the Home Office.

This measure was introduced last November as one of 61 commitments made to the Government's Serious Violence Strategy.

The Dartford MP also spoke on this, reassuring residents that the Government is working hard to try prevent any acid attacks in the future.

"The possession of some noxious substances is being made illegal and sales will be restricted.

"It’s hard to think of a more cowardly crime than attacking somebody in this way and we are determined to do everything possible to end this type of offence," he said.

Police are treating it as an isolated incident.

Enquiries are ongoing and anyone with information is asked to call 101, quoting reference 03-1016.
