The investigation has ended after receiving a report from the Canada Border Services Agency (CBSA) that several potentially explosive devices were found inside a vehicle.

At around 9 p.m. patrol officers with the Explosive Disposal Unit (EDU) were dispatched to the 2600 block of Wyndote Street West to report that there were two grenades inside a vehicle.


Police say the grenades were found when CBSA officers inspected a vehicle at the Ambassador Bridge International Border Crossing. It was reported that the grenades were submerged in “an unknown white powdery substance”.

Officials say the area of ​​concern was cleared before the police arrived and the driver of the vehicle was already in the custody of the CBSA.

Several roads in the area were closed to vehicles and pedestrians after the police arrived. The officials ensured that everyone was at a safe distance from any potential danger and the EDU reached the spot.

Police say that the investigation has not revealed the involvement of any other person in the incident. It was determined that no direct threat was made to anyone or the location in relation to the grenades.

EDU used a robot for the initial testing phase and received powder samples for testing. Police say it was determined the powder was not dangerous and did not have active properties.

Another EDU member ran into the vehicle and safely secured the grenades which were found inactive. A thorough search of the vehicle was carried out until the proposals were satisfied that no other threat existed.

The scene subsided around 4 pm and traffic was restored in the area. The scene was completely cleared and regular bridge operations resumed around 6 pm

Police say that at the conclusion of the investigation, no criminal charges were filed by the Windsor Police Service.

“The investigation revealed that there was no intention to damage or use the grenades for any nefarious purpose. The grenades were inactive, as such, were not subject to any criminal charges,” a WPS news release said.

The driver of the vehicle was identified as an adult man from the United States, but since no criminal charges were filed, he would not be named.

Following a CBSA investigation, the man was returned to the US where he was remanded in the custody of US Customs and Border Protection without incident.
