Police got quite the shock after getting a call reporting a “Komodo dragon” living inside a Bay Area home.

Officers from the Alameda Police Department and members of animal control responded to the scene and discovered that the reptile had been abandoned there by former tenants, police said.

A photo released by police showed the crafty creature hanging from a set of venetian blinds inside the home.

Upon further inspection, investigators found the scaly suspect was actually a young Ornate Nile Monitor, which can grow to 7 feet in length.

“They have powerful bites, strong claws, and forceful tails that can cause injuries,” the police department said. “For these reasons, Ornate Nile Monitors are not suitable for beginner reptile keepers and are never appropriate pets for children.”

The large lizard is now living at Berkely’s East Bay Vivarium.
