A maniac was arrested Friday for snatching the severed leg of a person who had just been fatally struck by a train in California, police said.

The man removed the limb from the tracks at the local Amtrak station in Wasco, a city roughly 25 miles northwest of Bakersfield.

Wild footage posted to X shows the sicko closely inspecting the leg, even appearing to sniff it, in the middle of the sidewalk.

He appeared unconcerned by the responding police or the bewildered bystanders filming the revolting scene, and gave a brief wave when he spotted the cameras.

The crazed man then took off with the leg, swinging it nonchalantly as officers closed in.

Officials identified the man as 27-year-old Resendo Tellez, who was arrested on multiple outstanding warrants and for taking evidence from the scene, the Kern County Sheriff’s Office said.

A pedestrian had been struck by a train at the station before 8 a.m. The unidentified victim was killed and their leg was severed, according to officials.

The incident is under investigation.
