London CNN —The teenager charged with the murder of three young girls in a July stabbing attack at a dance class in northwest England will face a terrorism charge, British prosecutors announced Tuesday. The new charges he faces in relation to the attack in the town of Southport, England, are in addition to three charges of murder, 10 charges of attempted murder and one charge of possession of a knife. “Searches of Axel Rudakubana’s home address resulted in an unknown substance being found – testing confirmed the substance was ricin,” Kennedy told reporters at a news conference. The attack on July 29 has not been declared a terrorist incident, the police chief said. The matter for which Axel Rudakubana has been charged with under the Terrorism Act does not require motive to be established.
