The Crown Prosecution Service announced Tuesday that Rudakubana has now been charged with production of a biological toxin — ricin — contrary to the U.K.’s Biological Weapons Act.
He has also been charged with possessing an Al-Qaeda training manual in contravention of anti-terror law.
He is due to appear at Westminster Magistrates’ Court Wednesday.
“Axel Rudakubana already faces three charges of murder, 10 charges of attempted murder and one charge of possession of a knife — all relating to the incident at Hart Street, Southport,” said Sarah Hammond of the CPS.
“The two further offenses relate to evidence obtained by Merseyside Police during searches of Axel Rudakubana’s home address, as part of the lengthy and complex investigation that followed the events of July 29.”
