Police in London, Ont., have charged four people after finding hazardous chemicals capable of making an explosive device in a home near Western University’s campus.

London Police Service said they were responding to a trespassing call from the university, which led to a discovery of the chemicals in a home in the University Heights neighbourhood, west of campus.

Police responded to the university on Jan. 24 around 1:40 a.m. after a special constable at the university arrested a suspected trespasser following a foot chase. Officers located a loaded handgun at the scene, according to London police.

Police determined that a second man had also been involved in the trespassing incident, and the investigation led them to a home near Chesham Avenue and Chesham Place. Officers found hazardous chemicals that were capable of being used to create explosives.

Two more individuals were arrested at the home, and technicians with the explosives disposal unit assessed the scene.

Police said the home has been under police guard since the incident and members of the public have been asked to avoid the area. The London police service said that its Major Crime Scene team is investigating.

Four people have been charged as a result of the investigation and remain in custody, police said.

Jerry Tong, 27, is facing charges of carrying a concealed weapon, careless use of a firearm, possessing a loaded regulated firearm, resisting arrest, breaking and entering with intent, and occupying a motor vehicle with a firearm.

Zekun Wang, 26 has been charged with break and enter with intent, and occupying a motor vehicle with a firearm.

Fei (Frank) Han, 25, and Feiyang (Astrid) Ji, 21, have each been charged with unlawful possession of explosives.

The London Police Service said it will be on the scene for an “undetermined amount of time” to conduct a search and safely remove the chemicals from the home using specialized personnel and equipment.

The incident comes almost six months after Ontario Provincial Police (OPP) found pipe bomb-making material after stopping a vehicle on Highway 400 whose driver was wanted by another police service.

OPP say an investigation revealed that the passenger in the vehicle was in possession of the materials, which were seized and handed over to the OPP explosives disposal unit.

Police arrested a 33-year-old individual who is facing charges of making or possessing explosives for unlawful purposes, possession of a weapon for a dangerous purpose, failure to comply with a probation order, and possession of a firearm or ammunition contrary to a prohibition order.
