London police are revealing new details in what they describe as a complex, multi-jurisdictional investigation connected to Western University, confirming additional weapons and explosives being located in Ontario and Quebec. During a media briefing Friday, investigators said recent searches in Ottawa and Gatineau led to the seizure of more firearms and explosive materials. Det. Supt. Sean Travis said warrants were executed at two locations as part of the expanding probe. “30 Chancery Court in Orleans and 24 Rue du Fanion in Gatineau, Quebec, were searched as a result of this investigation,” Travis explained. “With information that had been learned, it led to the further location of firearms and explosives.” Police said items seized during multiple search warrants suggest the accused were involved in manufacturing firearms and explosives. Despite the discoveries, investigators emphasized there is no apparent threat to national security. “At this point in the investigation, this is not a terrorism investigation, this is not a national security investigation,” said Deputy Chief Paul Bastien. “We have partnered with the OPP and RCMP to ensure they are informed, engaged and have the opportunity to provide their expertise and input.” Authorities also confirmed all four accused are current or former Western University students. They face multiple charges and remain in custody. Police acknowledged they are aware of videos posted on YouTube by one of the accused, which feature a pitch for a startup called MORSLAB. In one video, the individual describes technology related to drone detection and electromagnetic systems. Investigators add the videos form part of the ongoing investigation but would not comment on how they may relate to the case. The investigation began two weeks ago following a trespassing incident on Western University grounds and the discovery of a loaded handgun. That incident led officers to a home on Chesham Place in the University Heights neighbourhood, where chemicals capable of producing explosives were discovered. Police say more information is expected to be released as the investigation continues.
