Novichok poisoning attack house roof to be demolished in UK

London: The roof of the home of former Russian spy Sergei Skripal in the United Kingdom will be dismantled by military teams following

the deadly nerve agent

attack on him and his

daughter, a media report

said Tuesday.

British detectives believe Skripal and his daughter Yulia first came into contact with Novichok, a military-grade poison, when it was sprayed on the door handle of their property, allegedly by Russian agents in March.

The clean-up at Christie Miller Road, Salisbury, has been taking place ever since they collapsed on March 5, the BBC reported.

Wiltshire Council

has warned neighbours of about four months of disruptions.

Contractors will cover the house and garage with a "sealed frame", according to a letter written by the

council's director of public

of health, Tracy Daszkiewicz.

A military team will then dismantle and remove the roofs.

Everything will be wrapped and sealed before being removed from the site.

"When that work is completed, contractors will move on site to build a replacement roof for the house and adjoining garage."

She said the risk to public health remains "low", adding: "The priority is to make sure that the two remaining sites affected by the 2018

incidents are thoroughly cleaned and returned to

normal use as soon as possible."

Skripal, 66, and his 33-year-old daughter survived the attack which Prime Minister Theresa May said had "almost certainly" been approved by the Russian state.

Wiltshire Detective

Sergeant Nick Bailey is also thought to have come into contact with the poison when he searched their home.
