Nerve agent victim Charlie Rowley released from British hospital after poisoning

"The searches are part of the investigation to find out where Dawn and Charlie picked up what appears to have been a contaminated container disguised as a perfume bottle".

The source of the poisoning of Mr Rowley and his partner was from a small bottle found at his home in Amesbury.

The mother-of-one died in Salisbury District Hospital on July 8 after battling for life for nine days in intensive care.

Police continue to investigate how Rowley and Sturgess may have been exposed to the toxin.

Meanwhile, an inquest begins Thursday into the death of 44-year-old Dawn Sturgess, who was also poisoned with Novichok last month, along with her partner Charlie Rowley, not far from where the Skripals were found. Sturgess died earlier this month and Rowley reportedly remains in critical condition.

'I tried to console him and said that he needed to try and keep as strong as possible so he can recover.

"They [the investigators] are sure they [the suspects] are Russian", said the source, adding security camera images had been cross checked with records of people who entered the country.

According to London, former Russian military intelligence (GRU) Colonel Sergei Skripal, 66, who had been convicted in Russia of spying for Great Britain and later swapped for Russian intelligence officers, and his daughter Yulia, 33, suffered the effects of an alleged nerve agent in the British city of Salisbury on March 4. Moscow has repeatedly denied any involvement and accused the British intelligence agencies of staging the attack to stoke anti-Russian hysteria.

The U.K. has blamed Russian Federation for the attack, a charge that the Kremlin has strongly denied.

Ridley, the coroner, said samples taken from both Sturgess and Rowley tested positive for Novichok at Britain's defence research labs.

Public Health England medical director Paul Cosford has said Mr Rowley's discharge from hospital does not pose a risk to the public.

Rowley, however, will remain under police protection as detectives continue their investigation into how the couple came into contact with the nerve agent.

Rowley's brother Matthew told the BBC that the 45-year-old had told him the Novichok was contained in a perfume bottle.

It is noted that work in the toilets located in the Park Gardens of Queen Elizabeth, began on Friday, and on Saturday morning proceeded.
