Shortly after the incident was reported late Wednesday, Musk announced that a top Tesla team was investigating the explosion. Tesla's investigation found that the explosion was caused by "very large fireworks and/or a bomb" stored in the rented vehicle, not a malfunction in the car itself.
"The evil knuckleheads picked the wrong vehicle for a terrorist attack. Cybertruck actually contained the explosion and directed the blast upwards. Not even the glass doors of the lobby were broken," Musk said on X.
During the investigation, Las Vegas police discovered gas tanks and large fireworks mortars in the bed of the Tesla Cybertruck that exploded near the Trump International Hotel in Las Vegas, Sheriff Kevin McMahil said later in the day, also thanking Musk for all the information he and his team provided.
