UK police identify Russian suspects in Novichok poisoning case: Reports

British police have identified "several suspects" in the attempt to murder former Russian double agent Sergei Skripal and his daughter by poisoning them with a rare nerve agent, media reports said today, citing the outcome of investigations in the high-profile case that has hit UK's ties with Russia.

Skripal, 66, and his daughter, 33, who were discovered slumped on a bench in the English town of Salisbury on March 4. They were treated for exposure to the Soviet-era military-grade nerve agent Novichok and discharged separately from hospital several weeks later and moved to secure locations.

Police believe they came into contact with the substance via the door handle of Sergei Skripal's house.

Several Russians were involved in the attempted murder of Sergei and Yulia Skripal, the Press Association says.

"They (the investigators) are sure they (the suspects) are Russian."
