Las Vegas Metro Police received an unusual call Thursday morning -- two chimpanzees were loose and attacking cars in the northwest part of the city.
Police were forced to fatally shoot one chimp that aggressively approached officers and bystanders, said Officer Laura Meltzer.
The second animal was tranquilized and secured by animal control officers, she said.
The chimps escaped from a home in the area where they were subdued, said Bill Cassell, a spokesman for Las Vegas Metro Police.
An investigation is ongoing as to whether the resident had a license to keep the chimps, Cassell said.
