The teenager was charged with stabbing that killed three girls He was charged with producing the deadly poison ricin at a Taylor Swift-themed dance class in England and now faces a terror offense for possessing a jihadist training manual, police said on Tuesday.

Axel Rudakubana, 18, who is charged with the murder of three girls And 10 other people stabbed In July he produced the deadly poison ricin, which was later found in his home, Merseyside Police said. Police also found a computer file containing an al-Qaeda training manual entitled: “Military Studies in Jihad Against the Tyrants: The Al-Qaeda Training Manual.”

The new charges against Rudakubana relate to the alleged production of a biological toxin, ricin, in breach of a law banning biological weapons in the United Kingdom, and to “possession of information, namely a PDF file…, which is intended for a person, who committed an act could probably be useful or prepare a terrorist attack,” the police said. The latter charge is prohibited under the provisions of a British terrorism law.

Ricin is derived from the castor bean plant and is one of the deadliest toxins in the world. There is no known vaccine or antidote and kills cells by stopping them from making proteins.

Police stressed that the July attack was not classified as a “terrorist incident” for which a motive would need to be known.

Rudakubana, who police said was born in Wales, has already been arrested in three cases over the deaths of Alice Dasilva Aguiar, 9, Elsie Dot Stancombe, 7, and Bebe King, 6, in July in the coastal town of Southport in northwest England charged with murder.

He is also charged with ten counts of attempted murder of the eight injured children and two adults.

The knife attacks were used by far-right activists to stoke anger against immigrants and Muslims after misinformation spread on social media that identified him as an asylum seeker and gave his name incorrectly.

The violence spread from Southport and led to riots across England and Northern Ireland that lasted a week.

In a statement Tuesday, Police Chief Serena Kennedy urged the public not to engage in speculation about the case.

“Don’t believe everything you read on social media,” Kennedy said. “We must not lose sight of the families of Elsie, Bebe and Alice, who are still grieving, and the families of the children and adults who were hurt and affected by what happened that day. We must all do the right thing by them to ensure that the justice process is not compromised.”
