Three men arrested last week following a doorstep acid attack last month have been released under investigation.

A man in his 60s was the victim of a “targeted, isolated incident” when he opened the door of his home in Knights Manor Way, Temple Hill, Dartford, at around 4.50pm on Sunday, November 26.

The men — who are 26, 35 and 50 and all from Orpington — were arrested on suspicion of conspiracy to cause grievous bodily harm and conspiracy to commit fraud by false representation yesterday but have since been released.

Police spokesman Vicki Foster said: “The incident is being treated as targeted and isolated. Officers do not believe there is any risk to the wider public.

“Following the incident the victim was taken to a local hospital by South East Coast Ambulance Service and was treated for minor burns to their neck.

“Inquiries into the circumstances surrounding the incident are ongoing.”
